I've been to a good many consignment stores in the Triangle, and while I've found good qualities to all of them, the Stock Exchange is simply the best. The clothing is very fashionable... none of my friends can tell what I purchase there is used. They run great sales, they actually have a good many items from the designers they advertise to carry, and the staff is very nice. You can also earn reward money from purchases. I've never consigned anything there, so I don't know how easy it is to do that, but I greatly enjoy shopping there. I've been able to stretch my budget a lot further than I thought while building up a professional wardrobe for work.
Pros: great selection, high turnover, great styles
Cons: none come to mind
