I thought these touches were a step above what I've gotten from other tailors and I will continue to go to Diana for my alterations.

I moved to Sunnyvale last year and wasn't sure which alteration shop to try since there were…read moreseveral in the area. I needed two suede jackets with zippers shortened, and from the research I had done online, I knew it wouldn't be an easy job. The first alteration shop I visited immediately tried to discourage me from doing the alteration and suggested I buy new jackets instead. They repeatedly emphasized how difficult it would be to cut the zipper and work with suede. Then I went to Kim's, and the experience was completely different. I was welcomed with a positive, can-do attitude right away. She was confident about the work and even quoted me a lower price than the first shop. One week later, I picked up two perfectly fitted suede zipper jackets. The quality of the work is fantastic. I've already received several compliments on them, and I was especially impressed that the original zippers were preserved. they didn't alter the look of the jackets at all. I'm extremely happy with the results and will definitely be coming back!

The service was terrible. I took two silk blouses in for dry cleaning, and both were damaged…read more One blouse had gold metallic threads in the lace area, which were completely ruined. I have no idea what went wrong during the cleaning process. The other blouse came back with very obvious color shading and discoloration. What made the experience even worse was that the staff showed no apology or responsibility for the damage at all. Very unprofessional service. I would strongly recommend avoiding this store.
