Marion Cotillard showed up to the premiere of 'Blood Ties' at the Cannes Film Festival wearing a gorgeous, silk strapless Christian Dior gown.

It's no surprise that the actress, who is an ambassador for the French fashion house, represented the brand on the red carpet, and we're certainly glad she did.

The subtle graphic, color-blocked print was the perfect touch for the elegant dress, and the actress chose jewels by Chopard and a pair of pointy-toe heels to top off the look.
