It seems girls like the unexpected and like seeing people who look different (but cool/good at the same time).
If you dress in street clothes or cool clothes that everyone else is wearing i.e. following trends, it doesnt make u stand out especially when trying to open up to HB's. If u was to go out in a costume or something thats funny (but not uncool) it would draw alot of attention and depending how u work off that will affect ur success rates from person to person.
Xavier - Yeah the Afro worked for me back in the days too (I wish I still had it

lol, but i shaved it off to look more corporate).
