Transformation

She may be a twin, but Mary-Kate Olsen has developed a look all her own. "I think it's important to make your own style because it's an extension of your personality," she once told InStyle. Indeed, after sharing the role of Michelle Tanner on Full House with sister Ashley (not to mention starring in dozens of twins movies), Mary-Kate now lets her personality show with a bohemian take on beauty that ranges from her signature braids to dramatic makeup. Yet she still credits her early career for comfort with cosmetics: "We've been wearing makeup since we were nine months old."

Too cute! 3-year-old Mary-Kate split the role of Michelle Tanner on Full House with fraternal twin, Ashley.
