Jaws dropped when bodacious blonde Cameron Diaz walked the red carpet of the world premiere of Knight and Day in Madrid, Spain, wearing a gorgeously draped, off-the-shoulder Lanvin mini from the Spring 2010 collection with chain-embellished heels from the same collection.  While most of us can’t afford the hefty price tag on the French designer dress, RadarOnline has found a similar looking number, for a fraction of the cost from Foley + Corinna.

Foley + Corinna’s asymmetrical one-shoulder drape dress is constructed out of silk chiffon, and features the same one-shoulder look as Cam’s. Retailing for $450, it is a steal compared to the Lanvin mini!
