That's fine, but then these stores lose out on the more practical-minded customers (e.g. me) who might want to shop there but are afraid to feel embarrassed.

Stores should offer trendy looking glasses at the front that, when worn, cause hidden text to be revealed on the walls, on blank signs near shelves, etc. This could include: The gender of that area of the store, the price, recommendations of how to wear it (e.g. buttoned or half buttoned, cuffed or not, etc.) Lots of details generally associated with clueless people could be made available because the trendy shoppers (and general onlookers) wouldn't have to or be able to be aware of it.

(The glasses beep if removed from the store, to prevent people stealing them)
