Diane Kruger looked amazeballs at the opening ceremony for the Cannes Film Festival today. This Giambattista Valli gown looks so great on her. I love the color and this silhouette is perfect on her. I know this is slightly blasphemous, but I am getting a great Grace Kelly vibe. That's certainly not a bad thing. If you are going to mimic anyone, let it be Grace Kelly. Always.
