Shape
The use of sway, side stretch, and/or body rotation to focus your body more toward or more away from your partner. It is usually a small change in the relative positioning of your partnership to enhance or to extend a picture figure or to flow more smoothly into the next figure. It is a way to continue to "dance" through a section of music where you are not taking steps. Again, it is a small action, a feature of styling. If you don't do it, that won't interfere with your continuing to dance.
