try something that grabs their attention. I like to spike my hair up every now and then to grab the girls attention then they get close enough to see that I am actually good looking then I let my sense of humor/charm take over. Try wearing some clothes that stand out, but not in a bad or slutty way. Maybe bright colors like yellow or something, but it can't be ugly. And always be smiling. Look like you're having fun and a happy person. Nothing turns me off more than when I go to a party or club and see a gorgeous woman who looks like she's mad at the world.
