I'm going to let you in on a little secret. All guys in the beginning (ONLY in the beginning) view "female friends" as potential girlfriends. That doesn't necessarily mean looks are of high importance, but at least until we get comfortable in the "friend zone", every female whos phone number you have is viewed as somebody you could possibly hook up with at some point.
Well I'm not gonna lie, no guy really wants a dirty, dingy girl. But on the other hand, I don't want a top model Paris Hilton look alike. So one that just keeps their self in good hygine. Makeup for big fancy things but if I'm just taking her to the mall she don't have to be all dressy. Whatever makes her feel pretty.
