From the moment she broke into the Oscar scene with her role in 2007's La Vie en Rose, Marion Cotillard has been one of our favorite awards circuit fixtures. The French actress surprised us this year when she earned a best actress Academy Award nod for her role in Two Days, One Night and will likely shock us again when she hits the Oscars red carpet on Feb. 22.

Although the actress tends to favor Christian Dior—she is a spokeswoman for the Parisian house, after all—she is never one to shy away from a statement-making frock. From her voluminous sleeveless winter white Dior haute couture gown on the Critics' Choice Awards red carpet this year (top, right) to the edgy black and cream Christian Dior number with a peekaboo under-skirt at the 2012 AFI Fest (top, left), Cotillard's style is always classic but with an updated, modern twist. In anticipation of her walk down the red carpet this Sunday, we're taking a look back at her best red-carpet looks ever. See them now in our gallery.
