Over the Shoulder Look
Head turned over the shoulder.
Great pose to show off that "S" curve. Even if you don't have a curvy body, you can create the illusion of curves. This pose is ideal to show the back of the body when you're wearing a backless piece of clothing or one that has great details on the back. Also a great way to avoid showing that double chin we all hate.
