Face ofcourse. A woman could always work out the body or make surgical enhancements.
No amount of sit ups is going to fix a dog looking gal.
Remember the cartoon, one of the Bugs Bunny ones I think.
At the end of the episode, for his bravery, this dog wins the prize of the Chief's daughter for marriage. They slowly raise a curtain first exposing her legs, waist, bust, all with the dog drooling and whistling. When they finally show her face, she is hidieous and the dog starts running with her cackling chasing after him.
Or remember the movie Who Framed Roger Rabbit? Eddie Valient goes into Toon Town to find Jessica Rabbit. Instead he find Meana Hyeena. Same body as Jessica but a but ugly cross eyed fucked up face.
