Most Helpful Guy
It really depends on the girl.
For most, I'd say it doesn't work as it's very unfeminine.
But there are girls who seem to make the un-feminine thing work for them.
Sara Silverman, for example, is cute as hell but 5 minutes in her company and the one word that would never leap to mind is "feminine". She's also quite hairy. Not Robin Williams hairy, but hairy for a girl. It wouldn't surprise me at all if she had hairy pits, or a bush straight out of a 70's p*rno. (I don't think she does... I'm just saying it wouldn't surprise me if she did.)
I think she could get away with it, somehow. Like, it would suit her tomboy-ish nature.
