I dropped off two pairs of jeans and a shirt to be altered. The jeans were too long so I wanted them hemmed. The shirt had buttons on the cuffs that fell off. I got them back a week later - it seems like they have a lot of people coming in everyday.
The tailoring for the jeans was very good - I don't notice the seams at all yay. They ask you what inseam length you want it to be, and if you don't know, you can always try on your pants on-site and ask the tailor to pin it for you. However, I think they left this weird stain on my shirt - and I don't know how it got there. Overall, the pieces of clothing cost me $27, which seemed a little high. (Those two factors contribute to the -1 star) But they're really close to CMU (where I go to school) so I guess I'm paying for the convenience. Overall though, they do a good job and the staff members there are really nice :)
