If I can't mention the rack, I do like girls with a bit of muscle on them. Some nice definition in the arms, a vague but ever-present six-pack, but the legs should be thick, but without much muscle. I dunno.
Also, I love seeing a girl when they let their hair loose. I'm especially fond of long, silky hair, but for some reason I find a girl ten times as attractive if she keeps her hair in some sort of 'do that binds it all up somehow all day, then she just lets it all hang loose when we're alone. Kind of like how some guys like girls with glasses, cuz the second they take them off, their facial features become that much more significant.
