With her feline blue eyes and cloud of chestnut hair, Marion Cotillard epitomizes ladylike, timeless glamour. She’s always put together but never overly so, usually choosing simple, womanly cuts with a nipped waist, minimal neckline, and full skirt. Despite her affinity for classic silhouettes, she always manages to look modern with interesting fabrics and touches of sparkle. As a face of Dior, she has access to some of the most amazing clothes that current fashion has to offer — indeed, she was the first person to wear a piece from Raf Simons’s first Dior couture collection on the red carpet — but she always wears the clothes, not vice versa. When she’s not on a red carpet, she dresses for comfort and function, opting for jeans and boots and warm coats. Enjoy a look at her fashion evolution over the years in our slideshow.
