Okay, that's a cop out I just can not allow to continue.
Yes, true, everything has to fit. I think that's true on some scale for every man who looks at women. Even if you're a guy who loves long legs, legs that are too long for the rest of her body just won't cut it. Also, even the breastiest of breast men need the rest of her body to be par.
I'm not saying you have to give me one part that you look at without care for the rest, but I'm SURE there's one part of a woman's body which carries more weight (heh) in what you find physically attractive. A breast man can appreciate a nice smile too. A hair man can look longingly at a nice pair of legs.
But there's always that one part.
