Extreme comparison between a woman with a very small jaw, and another with a very large / square jaw.
See how Marcia Cross jaw is much bigger than the one of Eva longoria.
You can notice in this picture the much bigger asian jaw of Joan chen (on the right). Asian women jaw are often so much bigger !!
The two pictures where taken at the exact same scale for a fashion magazine. Although the ears and nose from the model on the right are larger, Aurelies's jaw (on the left) is much larger.
