If you look at it from an evolutionary standpoint, men look for a fertile female (a certain waist to hip ratio is a good indicator of fertility – Marilyn Monroe is a good example of a figure in that ratio), women look for a male who will give her offspring the best chance of success. As a human, that means a successful man who can easily provide for all of the needs of her children. Further, we both look for symmetry in face and form.
Having said all that. I did not care that my (future) husband was stacking produce when I met him. He was hot (and still is)!
