I seem to have shorter arms than the average guy. Whenever I get a new coat, the sleeves always end up being too long. It makes me look like a 5 year old trying on daddy clothes. Because of this, alterations are something that aren't unusual for me to get.
Over at Come & See Alterations, I've had a few hems done along with sleeve jobs on blazers. Prices were reasonable and can vary upon garment type.There's also an extra 10% off for being a student.
They've always done a good job and got things done promptly. This one time I took in my blazer, the woman could tell that I needed it done quickly. Instead of having the 2-3 waiting window, she said she'll have it done for me the next day. It's special service like this that'll keep me coming back.
