I have a corset dress so not much was needed other than a slight hem on the length. I'm giving one star for the sole purpose of them at least returning the dress back to me. Super disappointing. Not only was my dress NOT ready at 10 am Pick up time. It ruined my whole day with appointments I had scheduled. The hemming was terrible for the price, $200. My grandma had to help me hem the dress all over again! This should have been the least of her worries. This place had no sense of direction for the stitch. They sewed over my zipper so I could not even put the dress on. I would not say this is a professional place. On the contrary. DO NOT take your dress here. Not worth it! Save your money.

My experience with Ace Alterations was perfect! Sunny was so helpful and patient in helping me get fitted. She took in the waist perfectly to give me the best shape and fit. The dress was ready on time and I was very satisfied with the customer service and price.

I dropped off my wedding dress in May for alterations, fittings, adding a hem, cups, boning, tape, back tie, bustle, and hook. I paid a $200 deposit. The seamstress initially said it would be ready by 7/23. When I tried on the dress, I mentioned it wasn't tight enough, but she insisted it was fine. When I'm getting ready to pay for whatever she did, she insisted that I pay an extra $120 for the slit that she already mentioned when I took it in. Mind you, she was running back and forth rushing to press my dress. It was wrinkled and wasn't the experience I would have pictured. She did not press the dress as requested. The final cost came to $720, which was more than expected. I was not satisfied with the lack of professionalism and attention to my concerns. So for the lack of concern and attention, I'd think twice before going here because when you're planning an expensive wedding and need a dress to be done right, get someone that is as concerned about it as you are. Now I'm running around looking for a last-minute dress because this dress doesn't fit as expected when I took it in.

New leaf bridal referred me here and my wedding dress came out perfect. I asked her to make me look snatched and she delivered! It fit like a glove.

I HIGHLY recommend Ace Alterations to anyone and everyone! I had my wedding dress altered here and it was such a pleasant experience. Sunny took my dress and made it fit like a glove, she is so skilled. She also charged a very reasonable price and was professional and efficient throughout the process. I was comfortable and secure in my dress for a long night of dancing thanks to Sunny! My brother had his tux altered here and my sister in law also took her wedding dress to Sunny! She deserves more than 5 stars. Also to note- she will absolutely open on a Saturday for you if you ask and schedule ahead of time with her. So accommodating!

Did an amazing job on my wedding dress and my dress fit like a glove. She's very good at what she does and I highly recommend her to anyone.

I was referred to Sunny by a girlfriend of mine who has had a handful of alterations done by her. Two months before my wedding, I unexpectedly got pregnant and needed my gown altered STAT. Sunny was able to install a corset and take in the sides in such a short amount of time. And because it was cutting it close to the wedding date, she even offered to steam/press the dress for me as well at an affordable price. The whole experience from beginning to end was great. Professional and affordable prices. I will definitely be going to her for all my alteration needs in the future. Thank you, Ace Alterations!

My beautiful wedding dress.

Sunny hemmed two pair of pants. Fair price, on time and excellent quality. Top it off, she is a very sweet lady. I'll be back...

After nearly two decades of having my suits tailored by my longtime Italian tailor, I was honestly…read moreworried about finding someone who could match the same level of craftsmanship and attention to detail when he finally retired. A great tailor is hard to find, and when you're used to a certain standard, it's not easy to trust someone new with your clothing. Before he retired, he strongly recommended Simona and A-Plus Alterations here in Rancho Cucamonga--and I'm so glad he did. Simona has been absolutely fantastic. From the moment I started bringing my suits and other clothing to her, it was clear that she takes real pride in her work. The quality of her alterations is excellent, and she consistently delivers results that fit perfectly and look professionally done. Her attention to detail, skill, and experience really show in the final product. What I also appreciate is the personalized service. Simona takes the time to understand exactly what you're looking for and makes thoughtful recommendations when needed. It's the kind of service that's becoming rare these days, and it makes a big difference. On top of that, it's a family-owned and operated shop, which gives the whole experience a very welcoming and personal feel. You're not just another number walking in the door--they truly care about their customers and the quality of the work they provide. If you're looking for someone local who does high-quality alteration work and takes pride in their craft, I highly recommend Simona and A-Plus Alterations in Rancho Cucamonga. Whether it's suits, formalwear, or everyday clothing that needs tailoring, she's someone you can trust to get it done right. I'm grateful my previous tailor pointed me in her direction--he was absolutely right about her.

Everything went well she hemmed them. She was done when she asked for the price that she wanted…read morecan't ask for better.
