Rachel McAdams struck a pose at a photocall for her latest flick, "Midnight in Paris," (Directed by Woody Allen) in an embellished little white dress at the 64th Cannes Film Festival on May 11.

The actress opted for a Maxime Simoens spring 2011 couture frock with flowers at the shoulders and waist. Her accessories -- nude peep-toe Ferragamo pumps and single cocktail ring -- were perfect choices for her simple and sophisticated daytime look.

The blonde babe -- who has rocked voluminous, Brigitte Bardot-inspired hair in the past -- wore her locks in loose waves and donned subtle makeup. We adore her pink pout paired with lush lashes and rosy cheeks -- not overdone, McAdams looked radiant and beautiful.

The romantic comedy kicked off the Cannes Film Festival and the "Elle" cover girl was joined on the red carpet by her co-stars Owen Wilson, Adrien Brody and Michael Sheen.
