She is super good at what she does. Ive done prom dress, suit pants, and jeans. There's a small change room to try on so she can measure for you.

I honestly didn't think my clothes could be saved, but Express Alterations proved me wrong. I…read morewalked in with a pair of pants that fit like they were designed for a completely different person. They were too long, too baggy, and somehow made me look both shorter and wider at the same time. After bringing them to Express Alterations, they came back fitting perfectly. It felt like I had a brand new wardrobe without having to buy anything new. The staff was friendly from the moment I walked in. They listened to exactly what I wanted and somehow understood my confusing explanation of "make it fit better but not too tight but also not too loose." They were professional, patient, and clearly knew what they were doing. I left feeling confident that my clothes were in good hands. The turnaround time was also impressive. I expected to wait forever, but they finished much faster than I thought. When I picked up my clothes, the quality of the work was amazing. The stitching looked great, everything fit perfectly, and there wasn't a single thing I would change. It honestly looked like the clothes had been made for me from the start. I brought in one item expecting a simple alteration and left feeling like I had received a full makeover. My friends even noticed the difference. One asked if I had lost weight. Another asked if I bought new clothes. Nope. It was just Express Alterations working their magic. The prices were fair, the service was excellent, and the results exceeded my expectations. If you have clothes that don't fit right, don't throw them away and don't let them sit in your closet collecting dust. Take them to Express Alterations. They turned my fashion emergency into a success story and probably saved me from wearing badly fitting clothes for the rest of the year. Five stars. I would definitely come back again, especially the next time I accidentally buy the wrong size and convince myself it will somehow fit when I get home.

They don't do dry clean so you know they must be good at what they do to pay rent with just alterations. These are elite tailors that you can trust them with high end garments.

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.
