We like to think of our bodies as unique and totally different in shape than anyone else's body, especially in regards to our posteriors, but according to NYC plastic surgeon Matthew Schulman MD there are actually only 5 different types of butts out there.
And learning which type of butt we have can help us choose the right underwear and clothing that looks flattering on our fannies (the American usage, not the British).
The five basic booty shapes are square, round, V-shape, A-shape and upside-down heart, a list which Schulman MD formulated after examining "an estimated 50,000 butts from 35 countries and almost every U.S. state":
Dr. Schulman says your butt shape is determined by the placement of your pelvis and hip bones, the amount of fat you have and its distribution, the size of your underlying gluteal muscles, and the way your butt muscles attach to the thigh bone. The outcome is a butt that fits into one of five categories.
