The Daring Dresses At The 2021 Cannes Film Festival

You'd think denim on the Cannes Film Festival red carpet would be a big no, but if you're Marion Cotillard, you can pull it off. After all she didn't wear jeans, her denim came in the form of a floral Chanel number from the brand's pre-fall collection. Paired with beautiful, dangling crystal earrings, she pulled off the unexpected look expertly. Would you really expect anything less from the French actress? Probably not. 

She was all over Cannes this year in memorable ensembles — she also wore overalls (Chanel ones, obvi) to a photo call.
