As the saying goes, when in Rome, do as the Romans do... and Marion Cotillard appeared in her Paris hometown for the Public Enemies premiere wearing none other than her fav Parisian designer Christian Dior! This was inevitable.. and there really isn't much more to add, other than doesn't she look great? The shape of the dress is John Galliano's vision for Fall 2009, and get ready for some retro chic - if you like the prim, proper & ladylike look, this is totally for you!

She paired the dress with some marvelous Galliano red sequin shoes (we're so not in Kansas anymore, Dorothy!) and stunning Chopard jewellery. While I know she IS French, no celeb does French chic better than Marion Cotillard right now. Enjoy the gallery, I'm off to have a cafe au lait avec une baguette (cos I'm feeling quite French now myself).

And to get you in the mood for Dior, how about the Fall 2009 runway show? Also below...
