Which look is a 10 on Nine star, Marion Cotillard?

We’re so happy Marion Cotillard has been making the party rounds celebrating her new film Nine as well as her Golden Globe nomination for her role in it. The French beauty always looks flawless and we love that she switches up her look often. Case in point, her sexy spirals she sported at a Dior cocktail party in LA on Jan. 9. Quite a contrast to her sleek hair at the NYC Nine premiere on Dec. 15. Marion always has that certain je ne sais quoi about her but which look do you think suits her best? — Marta Topran
