Diane Kruger in Giambattista Valli Couture | 2012 Cannes Film Festival Opening Ceremony & “Moonrise Kingdom” Premiere

It’s only the first day and Diane Kruger has already made her fashion mark on the 65th Annual Cannes Film Festival.

In the morning she rocked a sexy laced-up mini dress for the jury photocall before gliding down the red carpet this evening — for the opening ceremony and premiere of “Moonrise Kingdom” — wearing a beautiful aqua gown.

The 35-year-old actress was striking against the French Riviera back-drop in her custom made Giambattista Valli haute couture one-shoulder silk gown.

An attached sash at the shoulder cascaded down her arm and over her back.

Diane put the finishing touches on her look with a elegant up ‘do, dazzling diamonds and a crystal Judith Leiber clutch.

Pretty pink satin, peep toe platform sandals peeked out from beneath her gown.

What did you think of Diane’s opening ceremony gown? Is she off to a grand start?
