Look at whether you have an hourglass body. This is the least common with only 8 percent of women. The hip and bust measurements are usually equal, with a narrow waist. The defining characteristic of hourglass figure is a significantly defined waist with more or less proportional top and bottom. Hourglass shapes tend to be "curvy" both on top and on the bottom. You can still have an hourglass body even when: slightly fleshy upper arms, wider looking shoulders, or a slightly fuller bottom.
