The best actress nominee stunned in a white floor-length gown which she paired with glittering earrings.

Marion Cotillard walked the red carpet in a gorgeous white eyelet Christian Dior couture gown featuring bold back detailing at the 2015 Academy Awards held at the Dolby Theatre on Sunday (Feb. 22) in Hollywood. 

The French have a reputation for being better at elegance than the rest of the world, and Marion Cotillard is all about bringing reality to that perception. Whether she's playing chanteuse Edith Piaf in La Vie en Rose (2007), or a double amputee in Rust and Bone (2012), the native Parisian's innate grace and style never falter.
