Dakota and Elle Fanning
Who they are: These blond beauties have been acting and modelling since they were able to walk. Dakota has starred in over 30 films, including Man on Fire, The Runaways, and the Twilight saga. Elle is hot on her heels.
The Fanning sisters have garnered tons of praise for their high-fashion sensibilities and have become well-known for their sartorial choices. They've worn everything from Marchesa to Rodarte to Marc Jacobs and always look gorgeous and ethereal.
