It's less about a boy's look than it is about the way he holds himself. It's easy to tell if a guy thinks he's hot stuff or not. Also if he has that air about him that says, 'I don't care, I'm not gonna try to impress you', it's very attractive to me. And I hate guys who are always out on the prowl, those disgusting ones who are able to degrade women with just their eyes.
With that being said, I do normally go for guys with eyes that stand out seeing as eyes are normally the first thing I notice about people. That and hair; they have to have nice hair, which basically means it can't be too long and it looks well groomed. The last thing I normally make sure a guy has is style. I'm a big fashionista, so I'm always looking at the guys who know how to dress themselves properly. I can't stand boys who wear their baggy pants and think they look good with their underwear hanging out. Like, really... do girls actually find that attractive? If so, please inform me.
