Marion Cotillard was in Japan for the Tokyo premiere of her movie Rust and Bone, and for the occasion, she chose a look from Christian Dior's Pre-Fall 2013 collection. The beautiful strapless floral gown was not only in the prettiest shade of purple, but also featured a rise-and-fall hemline, too. As the face of Lady Dior handbags, we spotted Cotillard in a plethora of Christian Dior looks throughout award season, and it looks as though she's keeping her loyalty intact. Watch on for all the details. On Allison McNamara: Growze blouse, Vince Camuto blazer.
