Pale and dark hair is like a generic goodie.

Medium length hair is best.

Vaguely-goth/punk/emo look is cool. 

Tattoos and piercings are meh.

Intellectual ftw.

But honestly it really doesn't matter too much. If you were pretty much not fat and your tits don't look like flapjacks nailed to a wall, you could talk me into it.

EDIT: Specific body type? ¯\_(ツ)_/¯ Curvy? Nice hips? Idk.
