Rachel McAdams Dazzles in Sheer Lacy Red Dress at Cannes Film Festival (PHOTOS)

Oh la la! After stepping out in a white dress earlier in the day, Rachel McAdams made a quick wardrobe change for the Midnight in Paris premiere at the 2011 Cannes International Film Festival.

Rachel looked radiant wearing a curve-hugging, sheer lacy red gown, as she  stepped out alongside her costar Owen Wilson and director Woody Allen.

Earlier in the day, Rachel dazzled at the film’s photo call, wearing a white shift dress and nude peep-toe heels.

Midnight in Paris is a romantic comedy that follows as family as they journey to Paris on business. The city forces one engaged couple to face the fact that a life unlike their own might be better.
