Best Dressed: Vanity Fair Oscar After Party 2012

One dress is not enough for the celebs who attend the Oscars, so here's a look at my favourites from the Vanity Fair Oscars After Party, taking place as we speak.

Rosie Huntington-Whiteley in Antonio Berardi; Lily Collins in  Monique Lhuillier; Sofia Vergara in Roberto Cavalli and Katie Holmes in Lanvin. 
But for me it has to be Cameron Diaz in this gorgeous Gucci number
