Guide to american clothes - girls (and guys, of course!

hi! i started to buy about a year ago here and must say, i'm a huge fan of american brands. the fabric is longwear, models are simple and very comfortable, colors are saturated. i have some af, hco, ae, forever 21, anthropologie, gap and cannot complain. but not long ago i've found that: 1) these brands are preppy, as i understand, clothes for high-schools | college students. i'm 30. am i too old for them? i also have some rl and lacoste e.g. but i do not feel hot and comfy in it, don't know why. just a obvious, boring clothing for me. 2) af and hco are racists and proud-to-be-white guys buy their clothes for accent. is it a myth or is that true, really? i'm in shock because i'm liberal and love af, high-quality clothing by the side of zara, mexx or benetton, overpriced and cheap quality here. I don't think there is anything wrong with someone who is 30 wearing those brands. Wear what you are comfortable in! I don't totally understand your question about the clothing companies being racist (?) But, I will say that pretty much all of my black or hispanic friends wear Hollister. Abercrombie isn't big around here so I couldn't tell you on that one. I see guys/girls of every race wearing American Eagle. Maybe it's just where I live, but there are "preppy" people of every race that wear those brands, just as there are people of every race with a more "urban" style that wear urban brands, etc etc with every style of clothing there is....
