The video is just a preview of the Fall 2017 collection. Gainsbourg appeared front-row at Anthony Vaccarello’s debut for the brand last fall along with her sister, Lou Doillon, and her mother, Jane Birkin.

Gainsbourg recently promoted her new film, Ismael’s Ghosts with Marion Cotillard at Cannes Film Festival. She wore a sparkling pewter minidress from the same collection to the premiere.
