How would you know Rene? Aren't you a verified Female?
my "white guy's fantasy" is a different one. i am not a fan of name-calling, yet others enjoy that. Also i prefer a more classy style of dressing than a trashy "street h00ker" look. Again others may see that differently.
This thread's title and the question posed is "How Should Your BBC Slut/Whore Dress in Public?" What is that supposed to mean? Isn't it part of the question for the Woman how to send out a message to Black men in particular? ImO the question implies two aspects: First, a more revealing or "slutty" style, and second, like i already mentioned, how to let Black men know the Woman's interest for them.
Any outfit chosen to attract any heterosexual man alone is ImO not sufficient for what's requested by the OP. - It is a matter of the thread's topic and not a "white guy's fantasy." just sayin'
