It would save me money, which is how the owner explained it to me. Thank you for taking the job and then charging me an arm and a leg for the work.

Needed to tighten the waistline and I also wanted to trim the dress length so it'd reach the top of my knee - Late October 2025: I got my Maid of Honor dress altered here! Unfortunately, I had very vague ideas of what I wanted. No more than 10 mins on the fitting platform and this gentleman was able to piece together alterations I was extremely happy with when I had to wear this dress less than a month later. - April 2026: I got 2 of my new trousers hemmed here. I had pants from Banana Republic and Aritzia that fit well for my waist, but I needed to shorten the length for the pant legs. Although there's a bit of a language barrier, this man is extremely talented and a local treasure to the Diamond Bar community. I no longer live in the area, but he's worth the drive from the South Bay for PERFECT alterations. Most places have drastically increased their rates because of the pandemic, but I've never quarreled with the owner of Diamond Bar Tailoring. Fair prices for absolute phenomenal work!! He may not have the 5-star rating on Yelp he did back then in 2019, but he's always been consistent and great with managing his time/customer expectations. I have a deep respect for his craft and genuinely give him a "10/10 a would recommend."

I can't compare pricing to other places as this is the only business I've been to for these services, but it never breaks the bank and she accepts different payment methods. Her hours are limited but with the amount of people that pick up and drop off clothes when I'm there, it makes sense why. And if you're lucky you might get a visit from her puppy as well :) Only reason I dropped a star is that it's a tight space when there are several people there.

Gabriela is AMAZING!!! I had my wedding dress altered at another boutique but it still didn't fit…read morethe way I wanted, it was really loose and didn't fit well in certain areas, and with only less than a week left til our wedding I couldn't go back due to the time. I found Gabriela on Yelp and she does at home visits which was a HUGE help. She was on time and quick with her alterations. As soon as I put on my dress she knew exactly what to do and how I wanted my dress to fit... she made it fit like a glove! The bra cup was an issue as I bought it off the rack and was huge on me even after my prior alterations. She made my dress look so much better with to her alterations. I wish I had found her to begin with but I didn't do enough research. Ladies, take your wedding dress to Gabriela, you will NOT regret it!
