I am so traumatized from my experience here. I brought in two pairs of jeans, tags still attached, to be hemmed. Brought in an already hemmed pair for reference so they could measure the inseam. All good. She measures, tells me how much, I pay, then she takes down my info. As I'm writing it down, I hear ripping as if she's ripping off the tags. I dismissed it in the moment because the tags were in the waist and that had nothing to do with the hem. I even told her not to remove the tags. I felt really uneasy about it though, to the point where I went back an hour later to get the jeans back. She had removed the tags, but saved them. I was furious as this was done without my consent. I have incredibly sensitive skin and the plastic fastener that attaches the tags often gets trapped between the fabric with no way out when it is ripped. This is why I had left the tags on so I could remove it myself. I have had to throw away jeans before because the little tab of the plastic fastener irritates my skin. I cannot explain how annoying and inconvenient it is to have skin this sensitive, but I do my best. Unfortunately, I have to get pants tailored because I am so little so skipping the hemming isn't an option. I used ChatGPT to explain what was wrong and she kept arguing with me rather than take accountability. She then started stopping people walking by into the supermarket to GOSSIP with them about what was going on, and then stopped a few more to ask them to translate from Korean to English and back. Mind you, one of the people was this woman whose mouth was full of sores that looked really contagious and she touched everything including my jeans, the tags, etc. I was finally able to get Nosey Nancy with the Sores to go away, but the arguing continued. I'm not someone to get upset easily but she actually had me raising my voice and almost crying. I asked her to please open the waistband of the jeans to check for the plastic tab and she said she wouldn't be able to match the thread, to which I said fine. I eventually left. This happened today, 9/17/2026. I will update this review with more details on her work once she calls me to tell me the pants are ready. I'm never going back after this. Horrible, disrespectful, dismissive, gossip-minded, argumentative, and that's just her customer service. read more

Unpleasant experience, even though the owner and her employee were both nice people. I dropped off 8 brand-new items for alterations, including one dress quoted at $20. When it came time to pin the pants for hemming, I had to stand on a narrow stool in the tiny store with the shades only partially pulled down -- anyone walking by could've seen me. Not great. The employee wrote up the order (I photographed it as my receipt), I paid $97 total, and was told one week, back the following Friday, no problem. When I showed up, she looked at me like she'd never seen me before. Even after I reminded her, she was blank, so I pulled up the photo of the order. Then she claimed I'd already picked up everything except the dress -- not true. She climbed onto the stool, then onto a huge pile of clothing (shoes off, but still not reassuring when it's other people's belongings) and dug around until she found 3 of my pairs of pants. Then told me her boss had decided the dress needed $40 of work, not the $20 quoted. I wasn't paying more to leave with half my order missing. She called her boss, who said she'd be in 2 hours -- I couldn't wait. They promised to call when she arrived. Nobody called. Next morning I called just after 9 (they supposedly open at 8), she said 10 minutes, I said I'd meet her. My drive was 25 minutes and the shop was still closed when I got there -- waited another 15. She opened up, handed me one missing pair of pants, and insisted I'd already picked up the rest. I wasn't having it. She climbed the pile again and eventually found my last 3 pairs. She did refund the $20 upcharge on the dress -- would've been nice if she'd just honored the quote instead of making me fight for my own clothes across two visits. Can't recommend. read more

Jane is incredible! She's a quintessential professional tailor who operates an incredible shop, conveniently located with ample parking. She is reasonably priced and made my friend's suit cut absolutely gorgeous. I will drive across town to have Jane help me.. read more

First off, I was looking for a good alteration in K town. Really good one ! I have been going to my previous alteration over the years. Sadly, she is closing her business because her rent was going up. I FOUND THE PLACE !!! Jane, the owner she is working very hard. She even opened her place at 8 AM for people who could pick up their clothes earlier before they go to work. Plus, she is very professional about alteration. I went the first time for a leather jacket to fix. It's EXACTLY what I wanted. Secondly, her price is very reasonable. I went to another dry cleaning place in Western, and the lady was rude and tried to rip me off, just cutting the bottom of my dress. I was so upset about that. I would NEVER GO BACK THAT PLACE AGAIN. Alteration is important for clothes. It HAS TO BE RIGHT FIT ON A person. Jane knows exactly what customers want. I strongly recommend this alteration place in K town. read more

went to get some of my jeans altered - waist & length. super quick & great prices!! & the sweetest ladies ever :)

Can't beat her hours here. Shop right outside of H Mart. Thank you for seeing me late and providing a quick turnaround!

Ruined two of my garments, left items unwearable. I highly recommend that you go elsewhere for your tailoring needs.

I had a wedding to attend over the weekend and needed two dresses tailored. I was in a real time crunch and found Cosmo Alterations on Yelp. I followed the directions via Yelp but had to call her as she recently moved to a new location next to HK Mart at 124 N Western Ave, Los Angeles, CA 90004. It was right around the corner so it wasn't an issue at all. I stopped by and was greeted by the kindest lady I've ever met. I told her I needed the dresses done that night, expecting her to say no. To my surprise, she told me to go change and said she'd get it done. I'm so lucky to have found her! I will definitely be coming back for all my alternation needs. read more

The zipper on one of my favorite sweatshirts had broken and I brought it to Cosmos Alterations to be fixed. Jane P could not have been nicer and completely replaced the zipper for an extremely reasonable price. I would recommend Cosmos Alterations to anyone in need of personal textile assistance.

Jane did a wonderful job on a last-minute dress hem I needed! I called in the morning to see if they were free, I brought it in an hour later, and in three hours they were done. Very affordable, very fast! They work out of their home, so give them a call when you arrive. read more

Jane, the owner, is a hard-working lady who really cares about her business and satisfying her customers. I came into hem my curtains, and she was able to turn them around in less than two hours for a great price!! Will return for her service and her sweet demeanor. [Logistics: Don't be misled - this business moved next door about two months ago. Yelp photos of the exterior of the building show the old location. Don't punch in the business name on Google maps, because it will take you to the old location. Plug in the address posted on this Yelp page. The new location is in the same plaza as Biergarten. No need to valet your car; just tell the valet guy that you are dropping off/picking up from Cosmos and he will let you park in the lot.] read more

I had two issues timeliness and I hate saying it but the language barrier. Here's my story, I took in 3 button ups but let's talk about the one they messed up. The chest pocket originally was a bit long and literally came down to a taper, I asked them to make the bottom of the pocket round. When I got it back it was chopped straight across and there were long unsecured threads sticking out that I'm going to have to fix myself plus their thread line was a little wonky. When I first came in and explained what I wanted there was a lot of head nodding and "yes, yes, yes"'s, unfortunately she didn't understand. I realize at this time that this is the only negative review, I was impressed with their yelp that's why I chose them. When I went in, I wanted them to choose the day they could get the work done because I wanted them to do a good job. I dropped off my stuff on a Friday and they told me to come back the following Wednesday. I came back only to see that my shirts hadn't been touched. They told me to come back tomorrow. So, I came back Thursday and they told me to come back Friday. Mind you, it's hot and I had to battle traffic three days in a row only to be met with disappointment. read more

Cosmos Alteration - Sewing & Alterations Near Me - Los Angeles, California

I found Cosmos through a referral but I have gone back multiple times this year due to the consistent, talented work on all different materials. I received very meaningful, hand-me-down vintage pieces from my mom so I needed someone who would treat these with care and expertise. If you have any tricky or expensive clothing pieces to alter, this will be the place to go to get it professionally done at a very affordable pricing for the job. I advise being very specific about what you want, and when you absolutely need it by. The two things to note would be to 1) preferably bring cash or change and 2) call beforehand to make an appointment. The location is not a shop location where you can do walk-ins. Thank you all the tailoring! :) read more

I had a dress that did not fit and a wedding to get to at 7pm. I told the owner that I was so relieved I found her. It's not easy to find a place that does same-day alterations. She laughed and told me she would spend all night sewing if that meant meeting a deadline for a customer. She shortened my dress's straps, decreased the plunging cleavage, and shortened the dress' length. The total cost was only $25. The alterations were done with skill, and most importantly, she was fast! I dropped off my dress at 10am, and I picked it up at 3pm. She told me she could get it done quicker if I needed it. The owner seems to love what she does. She collects figurines of sewing machines, which she keeps on display. Also, she moved her shop to this location just one month ago, so I think it has been difficult to establish a customer base. I support this local business, and I am so grateful it is just a few blocks away from me. I will definitely come here again for all my tailoring needs. read more

Jane is sweet, talented, and efficient. I called her randomly and very last minute, she told me to come over at 2pm. She was ready to go at 2pm. I was expecting to wait for a few days to have my pants altered. Jane told me just to sit and wait for 15 minutes and she would have them altered. She hand altered my wool pants in 15 minutes for $15. I was very impressed. read more

I found this tiny place on Yelp and I'm glad I yelped! The owner is very sweet and she finished work on timely manner. It's not a fancy shmancy place but hey, as long as your stuff gets altered the way you want it, it does not matter right? It's a little difficult to try on your clothes because this place is tiny. Other than that, I was pretty much happy with the result. The ladies here don't speak English very well so be aware. Will be coming back again for sure. read more

Amazing tailor skill! It is my second time that I've been here. Every time the outcomes are very stunning! Jane's magic finger always make my dresses fit perfectly ！ read more

Cosmos Alteration - Sewing & Alterations Near Me - Los Angeles, California

CASH ONLY!! Small, little alteration shop located on western! There are 3-4 parking spots in front for customers. This place is owned by a sweet Korean lady who seems to only speak Korean. I brought in pants to get hemmed and she was able to hem them in around 15min! Great service! It cost $7 for a basic hem which is great. Only downside is that it's cash only. I didn't know but thankfully I had just enough cash on hand. Make sure you bring cash when you come!! read more

Went in to get 2 pairs of jeans hemmed. She did them same day. Very sweet lady and quality work. Will be coming back. I just parked on the street to get in easy and out. :) read more

What had started as a small pile of jeans had grown into a mountainous stack of neglected pants that remained NWT and too long for me to wear. My mom, shocked, intervene when she saw my Eiffel Tower. I was scared to part with my Elizabeth & James silk pants, Hudsons, True Religions, some nameless pair from Barneys, high-waisted pants from Seven, etc. My point being that this stack had cost a pretty penny and I didn't know if my mom's lady would do a good job. However, i pinned each pantleg to my desired length, begged my mom to run out if they couldn't do an original hem and left the rest to the universe. 12 pairs of jeans and $120 later ($10 for original hem, $5 for regular) I am a happy customer : ) I received my pants in mint condition, the hems are clean and the lengths exactly what I had asked for. Additionally, she completed my order in just 2 days so I could take them with me on my trip. Ms. Jane Park is amazing!! If you're looking for an affordable original hem, you should definitely give her a try. read more

Do not work with Jean, the boss. Work with others like Grace, who seems honest and her work is a lot better than Jeans. Jean lies, rushes, gives low quality work and pretends like she did nothing wrong. First, she overcharged me for the work that could have been done with other tailors for less than $20 but charged me for $25. I didn't want to argue for $5/10 bucks so I let it slide. But I should've walked away when she did that, but I stayed because Grace was excellent before. She overcharged me likely because she thought she can with me. Jean, the boss, without letting me know beforehand when I went to pick up my shirt, she told me that she changed the price to agreed amount of $25 to $35. This action by her showed her greed and likely illegal. I told her I would give $5 more as I didn't want to bother reasoning with the trickster. Jean seemed so happy that I even offered to agree to any extra raise when the original price was over charged to begin with. I tried my shirt that she worked on, and she over shorten the hem of my brand new $70 shirt. I told her it is too short. First she said the length is ok. When I looked myself with the shirt in the mirror I look like I am wearing a kid's shirt, too small. I insisted that it is too short and I compared with another shirt that I have at the time and it's about an inch and half shorter and I asked Grace sitting in the room and she said it's too short. Jean offered me to extend the length with the left over cloths that she cut off too much from my shirt. The solution of patching it up to lengthen the length of the shirt seem like a desperate measure but I let her try. After 5 min, the result looked ridiculous, Frankenstein helm that should not belong to anyone except who wants to sport that as a fashion, lol. Jean dared to say that it looks ok, and I should wear it as it is without worries. One thing to lie and another thing not to have any pride in the work that she does. I told her my shirt looks like crap and I can't wear it anymore, she didn't apologize or anything. I told her to keep the shirt, which I was way too generous, but I didn't pay for the work she did on my ruined shirt. She was happy to take my ruined brand new shirt, and I walked away from the place with a shirt short. I gave this place 2 stars because of others like Grace. Otherwise, this place deserves negative. Without Jean, I'd give this place 4. Stay away from Jean, she will rip you off as much as possible. Ask for Grace or others. read more

Jane is absolutely amazing at what she does. The first time I went to her to have some pants taken in, she explained to me that there are three points to her business model: She's fast, she does great work, and she does it for cheap. ...the latter two points are true. The sad reality is that she isn't reliable in terms of time. On top of that, she works six days a week, and she doesn't really take a vacation (as going to a Korean church is a job in itself). There will be nights where I'll get there at 5 or 6 (right after I get off work and fight traffic to Koreatown), and she'll have left for the evening or she'll have gone out on a delivery. If you can get your clothing to her, she'll do a great job, but whether or not she'll get your clothing back to you when she says she will is another story. So, here's my recommendation: If you live in the KTown area, there isn't anyone better. If you need it fast, forget it. If you want good work and you want to pay way below market prices for alteration work, this is the place to go. Also, her English is very limited. I've never had a conversation with her in English, but I've seen her struggle through a couple with other customers. She's genuinely nice, and her customer service skills are top notch. read more

This place is no longer present in the building. The owner lady runs the shop from her home. If you call the number here, she'll give you her home address which is actually only a block away from the original address. I'm not sure how other people feel about it, but I like having an actual store, so I stopped going. Based on previous reviews, she seems to be very good at alterations, and my pants that she did turned out okay. read more

I just got a summer dress altered by Jane. The pricing is reasonable , and she is very good at sizing adjustments. There are about 4 customer parking spaces right infront of the shop . The owner , Jane, is a sweet lady to make a little conversation with customer while waiting . She runs this business for years. Her skills are great . I will definitely come back again. read more

The ladies running this small shop are very sweet and more importantly do an awesome job. I had needed two pants to be altered at the bottom. The owner seemed to have lots of experience because I really didn't need to explain in too much detail. Her English is not so good, I would suggest to just go in and explain things to her in person, rather than explaining over the phone Will be back again soon, thanks so much! read more

She is excellent Taylor, she would do they way you want, but have to bare with her English. ( it won't be problem if you are willing to tell her what you want using body language :))) I left my bf shirts and pants even my white dresses which was so dirty(shame) but they came out so nice and clean. I highly recommend this place without questions!! read more

Update! She moved location. She's now at the Biergarten plaza. So I've been going to her for awhile now and I realized I don't like her. Cons -She's unorganized - Doesn't really keep track of how much she's charging you, so it's always different everytime you go. OR she'll ask you how much did I charge you last time? It's great if you want to swindle her but if you're an honest customer, she should know how much to charge. Also I just went this past weekend and she gave me the wrong pair of jeans to try back on after she had altered them. -Cash only -For non-korean speakers, she does not speak english so you're straight outta luck. Bring an interpreter. -I asked her to alter my jeans length wise and taper them, but she didn't do that great of a job. One side was more tapered than the other. It is my fault as I should have noticed this when I tried the jeans back on, but I was in a hurry, so I said it was fine and left. Either way she should have done a better job. Pros -The ONLY reason why I would go back and I have been going to her is because she will hem my jeans same day and to me that's very convenient. Perhaps that's why she doesn't do that great of a job because I ask to do it same day? I hate dropping clothes off and having to pick it up again. I'm more of a instant gratification girl. -I'm not an expert at alterations cost, but I think she's on the cheaper side. So there you go. Def go to her if you're not a perfectionist and need things hemmed same day. If not, I would check out other places that are more consistent. read more

She is kind and amazing. Because of the pandemic, she is currently doing it at her home. I will definitely come back again! AMAZING

I happened upon this little shop after being turned down by a couple other places for what I needed. I had three collared shirts that I needed altered to be Oxford style shirts (you know, with the little buttons on the corner of the collar). I was kindly greeted by the nice ladies that work here. While they didn't have the specific equipment they needed for this particular project, they gladly accepted my request and said they would outsource the work in order to get it done. The work took a little over a week and I received a call that the shirts were finished. I was very pleased with the alteration, and they even dry cleaned the shirts as a courtesy! The total, with the originally quoted price and a tip came to $36.00 which I gladly paid. (They accept Cash or Check) Ms. Jean Shin (In Sook) is delightful, and I will happily continue to take my business to her. I recommend this location for anyone who seeks friendly service, respectable craftsmanship and those who like to support small local business. read more

I dropped a dress off to be hemmed and when I came to pick it up on the owner said it wasn't ready and to come back at 10 pm (long after they had closed). When I arrived at the store it was closed and I had to excessively call the owner. When she finally picked up she said the dress needed more time and she had just gotten to the shop. When I walked in the dress still wasn't ready and that she had only just begun working on it. I had to sit in the store for 40 mins at night while she hemmed my dress that I had dropped off 4 days prior. read more

New location: better parking, better space. But the original review still stands, decent prices; but they don't keep the promised time. This was my second time, drove to ktown, only to be told it's not ready yet - just to hem some pants! read more

if i could, i would give them ZERO stars. I've had the worst experience with Cosmos Alterations and the owner is not professional. I was desperate to get my bridesmaid dress fixed. i went to Cosmos alteration and talked to the owner. she said she can fix it and took my phone number and a deposit. i was skeptical leaving a deposit despite seeing any of her work but i didn't want to argue. she quoted me a price that was more than i expected but because if the urgency, i was grateful. i was told by the owner to pick up my dress on wednesday. yelp said they open till 7 pm. the sign on their door says they are supposed to be open by 7 pm but i got there at 6 pm and they were already closed. okay. that happens. i didn't let it upset me and i left. they next day i left school during lunch at 11:30 am to try to pick up my dress again. strike 2. they were closed again! let me say, this was in the middle of the regular working schedule but there was a sign at the door this time. i called the number on the sign and talked to the owner. she said my dress was done and that she is very sorry and that i can pick it up anytime that night. later that night, i went there and this is how it went down. she shows me the dress and it was horrible work. i couldn't even believe she was trying to present this to me. you can see the stitches she did by hand. on top of that, my dress is pink and she used white thread. when i asked her about it, she had no words. the dress was a sweetheart cut and she tried to alter it and made it uneven. one side is heart shaped, the other side is straight. she again apologized and said they will fix it and make it even. i asked her "why did you make it the first try?" she just kept saying she was sorry and that she will fix it. she told me to please come the next morning. when i came back this morning to pick it up, it was worse. sweetheart wasn't fixed. she said she wasn't sure about cutting the fabric. she wasn't sure?! what was i complaining about? i asked her why didn't she call me? she had my number? and she just kept saying sorry. i told her.. next time someone comes in and you can't do the work. just say you can't do the work. if you have a question or you are not sure about something, call your customer. i will never return, nor do i recommend this place even to my worse enemy. if this was me a couple years ago, i would have made a scene, not pay and leave. read more

THE.WORST.ALTERATION.EXPERIENCE.EVER.!!!!!!!!!!!!!!! I know that writing this negative review won't change anything but there's really nothing else I can do to relieve my anger. Never been so frustrated with a business in my life. This was only my second time but first frustration starts out by not getting the work done by the date that she promised. I went to go pick up two pair of clothes on the date arranged and ends up searching for the other pair just to realize that she forgot to work on it. She charged me $30 to fix shoulders on a dress that I ordered online from Korea and $15 for shortening the length of my jeans. I thought it was overpriced in the beginning but decided to do it anyways. That was my mistake... I waited another day for her to finally fix it and tried it on as soon as I got home--only to find out that the shoulders do not match AT ALL!! I don't even bother to call and complain because I know she can't do anything about it since she had already cut too much fabric off. If the dress was cheap or if I was able to buy it again here I wouldn't even be nagging about it! She also runs out to catch me as I took off to ask if I had already paid or not (which I already did ONE day ago which completely throws it off and shows how disorganized she is) What a way to ruin it. read more

I've had multiple pairs of jeans hemmed there as well as some shirts and they did a great job. Jane is very nice and accommodating. Really cheap prices for a great result. read more

If you need anything altered, hemmed, adjusted or simply revived, Cosmos Alteration is THE place to go!! Mrs. Jane Park is the sweetest and provides top-notch, quality work. She's recently altered several vintage evening gowns and my mom's mink jacket. I purchased an over-size vintage gown several years ago and it had been in my closest for years. I brought it over and she knew exactly what to do with it. She ended up updating my dress into a shorter A line from an older H line look. Now, it's my favorite dress to wear! She also transformed my mom's older mink jacket into a trendy vest and the sleeves were transformed into a classic shawl. I was super impressed!! She does an excellent job and is very detail oriented and meticulous. You can totally trust her with all your high-end alterations and both the price and service are spot on. I'll post more pictures of my dresses but here is a picture of the shawl and the beautiful Mrs. Park! read more

This is a WARNING do not allow JANE SHIN to alter your nice clothes. I made some assumptions I now realize were big mistakes so I want to make sure others do not go through the same. I took my brand new, never worn, leather jacket in to get shortened sleeves and altered shoulders. Jane said she could do the work. She took "measurements" by using binder clips...I thought it was odd but also thought maybe that's what you have to use for thick fabrics. Jane did not take more then a few seconds to complete my "measurements" but I didn't question it I thought she was the professional. She quoted $60.00 as the price. She asked me to pay but luckily I thought quick enough to only leave a deposit of $20.00. I asked her for a receipt and she did not provide me with one. She said she had me in her notebook so it was fine. Make sure you get a receipt before you hand over the money.She told me it would be finished in a little over a week. A week later I call the shop and asked if my jacket was ready and I was told yes. I go to the shop and Jane is not there and my jacket has obviously not been touched (still had binder clips). I asked when it will be ready. They tell me to come back the following week. I call again Jane answers and tells me to come in an hour, so I do. Almost as soon as she pulled my jacket off the rack I could see what a bad job it was. Jane did not bother to tailor my jacket properly at all. She claimed she had fixed the shoulders and even tried to trick me into believing she had the shoulders done by showing me some random sewing inside the sleeve. I'm not a tailor but I can tell when something does not make sense. She also did not bother to do what a proper tailor would do by removing the zipper and THEN shortening the sleeve. Jane simply folded the sleeve, zipper and all and then sewed that together...it's bad. Jane also damaged my jacket. As I was examining the left sleeve I noticed a rip and pointed it out to Jane at first she tried to deny it, then she said "I don't care". She tried to change the subject by showing me some more random sewing and in doing that she also revealed a big stain inside the sleeve. This was a brand new jacket I know for a fact the damage was not there but again Jane could not be bothered. I left, I did not ask for a refund although I should have but I really just no longer wanted to deal with Jane. Beware. read more
