hello everyone. i've never had a tailor in my adult life, and some of the seams in my skirt are starting to come loose and a few things are starting to get old. i notice there are a couple of alteration shops in my area and because i am new to the area i don't know anyone in the area to ask which one is the best. so i wanted to ask you guys, what do you look for in a tailor before using their service? is there a book that they keep of their work you could look at? are there signs of someone who might not be that skilled? etc.
