How many times do you see a stunning girl with a pig-ugly bloke? Personally I see it all the time. I think theres only two things that matter looks-wise:

* Height
* Body

For some reason girls just love tall guys, and well built guys look healthy and like they're life is in order. Other than that I think look don't matter that much. They only matter in the approach, so for ugly guys I think indirect game is the way to go every time. Attraction for women doesn't happen instantly like it does for men, it happens over time as she gets to know the guy. I agree with Mystery that the ways to attract a girl are showing you are:

1. a leader of men
2. preselected by women
3. protector of loved ones
