WOW…Rachel McAdams really made an impact on the red carpet at the 2011 Cannes Film Festival “Midnight In Paris” Premiere tonight.

She wore a sensational Marchesa Fall 2011 gown.

The embroidered red silk organza illusion cap sleeve gown with tulle ruffle skirt is both romantic and dramatic in equal parts.

I love the retro waves we are seeing a lot of during Cannes so far, as stars are giving us old Hollywood glamour.

As much as I love the dress and the hair, I’m not too crazy about the Casadei pumps.

A very light pair of strappy sandals would’ve been preferred.
