My one sentence summary is that this is one of the most trustworthy tailors in town!
Kim runs this shop by herself with the occasional help from her husband (when he gets off work). When I was new to town, I tried about four different alteration shops and found Kim to be the most meticulous and reliable tailor in town. Her cuts are always clean, precise, and the stitch work impeccable.
Unlike most other shops that hire several mediocre workers to meet the demands of increasing customers, Kim has no intentions of sacrificing the quality of her work and personal relationships with customers. Needless to say, she takes her time with the alteration work (she usually asks for about a week if it's not urgent), and this can be the downside if you would rather get it in a few days. Other shops in town like Yong's and Noy Tailoring employ sufficient workers to get things done quicker, but I've had a few disappointing experiences with them: their stitch work is sloppy; sometimes they completely misunderstand my instructions; and it's apparent most the time they were more focused on getting it done quickly. At these shops that employ other workers, there often seems to be serious communication problems between the owner who takes the instruction from the customer and the worker who takes over the work. Also, the quality of work as I already mentioned is mediocre at best. For example, I've had a few $125 dress shirts taken in asymmetrically, and polo shirts shortened with the folded cuffs left un-stitched and threads hanging out.
If you want a tailor who takes the time to get to know you, listen to you, and actually does the work accurately the way you asked them to, Kim's Alterations is the best place in town. She will work with you until she gets it right. However, one thing to note is that because she works alone with a considerable amount of work coming in everyday, she will turn away some of the more difficult and lengthy alterations like fixing shoulders of men's suits (you should not be buying suits with ill-fitting shoulders anyway).
Kim's prices are also one of the lowest in town - so low for the quality of her work that I've been telling her to raise her rates! Despite demands from THE CUSTOMER to charge more, she still keeps it the same, so I always tip her when I'm happy with her work (99% of the time).
If you're new to town and care about getting someone meticulous to do the alteration work, Kim is the tailor you want to go to! But just so you know, she only takes cash or check. Still, I wouldn't go anywhere else!
