Walid is by far the best tailor in Charlotte. I found him through Yelp and other sites.
I've gone there several times with my high end items. After first testing him out with one of my more inexpensive sportcoats, I've gone back continually since. If you're a novice to getting your clothing tailored, he will explain exactly what he feels is needed. And he won't try to upsell you on anything.
It will be a little pricier than others, but it's worth it. A few extra dollars will be well worth all the compliments you get.
