Youd be surprised how accepting people are at clothing outlets, it is after all their job to sell clothes.
If your still super shy id suggest hitting up a walmart or a bigger box store, pile up some clothes on your cart and get a dressing room.
The most they do there is count the articles of clothing, and if they give you an odd look, return it lol they are what i consider single serving people and in no way will they ever affect your life unless you let them in.
