Maybe the girls who did approach you did so despite the fact that you're dressed and groomed like mental patient (I say that lovingly fellow HNer)
Anecdotal evidence is fun and all ("I have a GF so I must know everything about women!") but to think that wardrobe means nothing to the opposite sex is just crazy.
As soon as you enter the room your entire presence is scrutinized immediately by every woman (and most likely some men) in the room. Most won't need to even ask you how much you make after they approach you, they will have already deduced it from what you're wearing and your personal grooming (or lack thereof)
