The front of Marion Cotillard's dress is gorgeous but the back? Well, we're blown away.

On Sunday, the "Two Days, One Night" actress—who's nominated for a Best Actress award—walked the Oscars 2015 red carpet wearing a white Dior couture gown that had everything going for it: an unusual but flattering shape; a beautiful texture and a head-turning back that propelled her to the top of the best-dressed list.

A long train and a striking black band that hugged the back of her legs completed the stunning gown, which she styled with slicked hair with a major side-part and neutral makeup that showed off her natural beauty.

What do you think of Marion's dress?
