French actress Marion Cotillard went for understated elegance at Monday night's City Of Lights, City Of Angels French Film Festival opening at Los Angeles' Directors Guild Theater Complex. Cotillard chose Chopard's Happy Diamond yellow gold choker and a delicate multi-strand bracelet with gold citrine, blue topaz and diamonds set in yellow gold for this semi-formal affaire.

The busy actress pulling double duty in either sides of the Atlantic - last seen in the American flick "A Good Year" and the French film "La Môme" - kept the corps decor to a minimum (and the charm to a maximum) as she signed autographs for fans and mingled with friends/colleagues/lovers of everything French.

Opting for a simple floor-skimming strappless dress, Cotillard took the (tasteful) less is more approach....and left photographers and admirers with more than they could've hoped for.

Encore!
