Attention! It's a battle between a French and an American. Frenchie Marion Cotillard first wore Vivienne Westwood's red satin strapless dress to the London of Public Enemies. Ankle-strap platforms and a black Stella McCartney clutch went along for the red-carpet ride. Then 90210's Jessica Stroup showed up to the Vivienne Westwood Spring '10 show in Paris wearing the same dress, only with different accessories. Purple Brian Atwood platforms and diamond jewels were her accompaniments of choice. So, who's it going to be?
