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.
