Elizabeth Olsen doesn't have much in common with her famous twin sisters Mary-Kate and Ashley.

"I'm the curvy one of the family. It's very clear that I'm the younger sister," Elizabeth, 22, tells the December issue of Marie Claire. "My whole life they've been like women, while I've been trying to be a woman but still a kid."

Not that she needs it. The young actress earned critical acclaim for her breakout roles in "Martha Marcy May Marlene" and "Silent House" at the Sundance Film Festival. She also appears opposite Robert De Niro, Sigourney Weaver and Cillian Murphy in the upcoming thriller "Red Lights."
