Marion Cotillard Wears Sheer Dress to 'Roma Elastica' Premiere at Cannes 2026
Cotillard wore a semi-sheer black Chanel dress with a fringed train, as Cannes organizers enforced a no-nudity dress code.
- French actress Marion Cotillard walked the 2026 Cannes Film Festival red carpet at the Roma Elastica premiere in a nearly-naked Chanel dress, styled by Eliott Bliss.

- As a Chanel brand ambassador since Feb. 2020, Cotillard accessed the house's archives and completed the look with elongated, back-button diamond earrings from the Haute Joaillerie Sport collection.
- Bella Hadid defied Cannes dress codes in a semi-sheer crochet Schiaparelli gown, while Kristen Stewart wore a see-through dress from the Fall 2026 fashion show.
- The dress code simply did not apply to Chanel ambassadors this Cannes, and organizers might eventually walk back the rules entirely as celebrities continue pushing red carpet boundaries.
