Famous Younger Siblings

Lil Sis: Elizabeth Olsen, 23

Big Sisters: Mary-Kate and Ashley, 26

Before Elizabeth surpassed her tiny fashion-designing twin sisters, Mary-Kate and Ashley, in height, this budding actress -- who made her mark starring in the 2011 indie hit "Martha Marcy May Marlene" -- had access to one of Hollywood's most coveted closets. "For two years, I didn't buy anything. I've had this [grabs a huge gray faux-fur jacket] for two years. It was a sample from The Row that never got made. But even as a little kid, our parents made us go through our closets so often, so I had all their hand-me-downs," Elizabeth told ASOS magazine.
