Movie bombshells like Sophia Lauren and Marilyn Monroe had enviable classic hourglass figures, with amply proportionate busts and hips and small waists. Yet only about 8 percent of American women have hourglass figures, according to a study by North Carolina State University. A similar study in the United Kingdom found that a tenth of women had hourglass shapes, and that nine in 10 didn't know their own shape. It's helpful to know your shape and size so you can shop for the best fit and most flattering fashions, whether you're a pear, rectangle or a true hourglass.
