Luella Bartley is already doing a surf line for O'Neill - now she's also designing for Disney. The British designer joins Agatha Ruiz de la Prada, Azzedine Alaia, and Vivienne Westwood in making couture for Disney heroines, which will be auctioned off at Sotheby's for UNICEF. While Luella tackles Tinkerbell's clothes - shiny, sassy poufs and party-girl dresses - Vivienne is outfitting Snow White in black ruched cocktail wear. Other costumes include a Cinderella gown complete with combat boots, and a yellow strapless gown for Belle from Beauty and the Beast. Unfortunately, the dresses go on the auction block weeks after Halloween, but is there ever a bad time to dress like The Little Mermaid? Of course not!
