Booty Basics

Grace and Dolly are best friends and sisters, but they are total opposites when it comes to fashion. Grace says she's the more conservative sister who prefers streamlined, sophisticated looks. Dolly just likes to be comfortable and tends to dress sporty.

The sisters also face different challenges in the dressing room. Dolly says her butt is big and shaped like a "bubble," while Grace's butt is small and flat. "[My butt] disappears in jeans...it ceases to be," Grace says.
