I am a white girl with blonde hair and very fair skin, and on the short side (5'2"). I am looking to modify my clothing style to attract black guys because I am interested in a guy in one of my college classes. How can I dress to attract black guys?
Dress as you'd normally want to dress. There is no scientific study that say people of colour including blacks are attracted to women in certain outfits.
But anecdotal evidence indicates black guys have a strong affinity to busty, curvy or chubby girls compared to their non-black counterparts. If you have curves or hot bum, that could work in your favour.
But hey! Forget about your outfits. Just tell him, you fancy him. Job done. You got nothing to lose.
As a black man, I should say that the rules for dressing to impress are the same for us as they are for other men. The best way to attract more black guys is to hang around more black people. It's a win-win: you can celebrate diversity while exploring your "interests" simultaneously.
