Going only for the body, huh? Tsk tsk.
See, what I look for in a girl first and foremost is the face. I can get a pretty good glance into their personality that way, as well as how physically attractive they are. The way they act gives up a lot about their projected intelligence and to an extent their ambitions.
Very noticeable in 'airheads' (not specifically stereotypical blondes).
I also find that instrumentalists tend to rank higher in the intelligence, personality and ambition categories, though not necessarilly in the physical attraction category.
In other words, to base whether you'd 'hit it' based on a cropped shot of a female torso in a bikini shows a lack of depth on your part. You'll be missing out on the quality girls, and they're the keepers.
