Marion Cotillard's Oscars 2015 Dress Is Fabulous From The Back

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?
