Hot: Marion Cotillard does the mermaid

The surprise winner in the Best Actress category was French actress Marion Cotillard (for her role as the late Edith Piaf in La Vie En Rose). Marion gets top marks for pulling off this audacious gold and ivory crêpe mermaid gown with descending scales, specially created by Jean-Paul Gaultier himself. And we absolutely love the Swarovski necklace with it.

What to steal from her style:
A long, fine necklace over an evening gown is a bold move, but it really works here. Thumbs to to the glam hairdo, too, that shows off Marion's perfect red-carpet posture.
