my experience seems a bit different from many of yours. i have lived a girl pretty much since i was 12 and that same year i spent allowance i saved up on a couple of really pretty floral sundresses, a pair of shorts and top, underwear and some cute sandals. i went in dressed a girl already with my big sister and didn't have any issues. this was 13 years ago (i'm 25) and i live in a fairly large, progressive city so maybe it would have been different elsewhere but there's a reason sephora boys are a thing so maybe times have changed?
