Guys: what makes you attracted to a girl?

what body type do you like? what do you first see on a girl?

im a chik...but a bi chik so ill give my opinion neways...a chest that isnt flat is defintly a plus...being skinny but not rib showing skinny is a plus
a girl that tries to balance out her meals without making a fuss and plays a sport is good (I find non-preppie/girlie-girs attractive) and a girl that isnt self-centered is a def plus
oh and a good sense of humour...

I like a nice booty. she can have a flat chest if she has a nice firm a$$. but something in the chest doesnt hurt. ribs showing is sick though.
