Here’s some who knows how to rep designers from her own country on an international stage.

Marion Cotillard opted to wear a dress by French duo Lefranc Ferrant at the 2010 Toronto Film Festival this weekend.

She’s in town to promote her new movie “Little White Lies”.

Her LBD from Lefranc Ferrant’s Fall 2009 Couture collection is very simple apart from the flap detail on her shoulder.

Because this look is so simple I’m guessing Marion tried to add an edge to her look, by pairing her dress with Dior buckled ankle boots.

Not something I would’ve picked, but she’s making it work for her.
