For the movie's daytime photocall, McAdams chose to wear a crisp, white Maxime Simoens frock, which featured flower accents on the shoulders and pockets. She paired the look with nude peep-toe pumps, simple hair and pink lips.

She later upped the glam factor and turned heads at the "Midnight in Paris" movie premiere wearing an embroidered Marchesa red silk, organza cap sleeve dress with tulle ruffle skirt.

McAdams stars in the Woody Allen-directed film, which opened the annual French Riviera event, with Owen Wilson, Marion Cotillard and Michael Sheen, her rumored beau.
