Personality wise, I like dorky, nerdy, silly girls. Like a girl who can explain to me the theory of relativity, or all the numbers if Pi. Or a gamer girl. Or just a girl who can get me back on my feet when I'm down.
In terms of looks, I'd prefer her be fit, or nicely shaped, with some eye candy. Nice set of boobs, and a phat ass.
But what are the chances of that?
