Ashley and Mark-Kate Olsen—2012
The Olsen twins? Never heard of them. We kid, we kid. Of course, Mary-Kate and Ashley Olsen went on to become gazillionaires after the end of Full House, launching an incredibly successful line of videos, clothing, books, and whatever else tweens might want to buy. Today they are more into adult fashion and have been mainstays on both best- and worst-dressed lists.
