For Karl Lagerfeld, a fashion show isn't about just the clothes, it's a performance — and his Métiers d'Art collections are notoriously big productions. In accordance, the designer will be showing this year's in Rome today, and beyond the show will present a film, enlisting Kristen Stewart [1] for its starring role. The short, entitled Once and Forever, follows two actresses' portrayals of Gabrielle Chanel. Told through behind-the-scenes shots, costume fittings, and screen tests, Kristen Stewart is clearly a natural, as we can already see from the early sneak peek, slipping easily into the role of the iconic designer and reaffirming her long-standing relationship with the brand.

Just as Stewart became the face of the Paris-Dallas 2013/14 Métiers d'Art collection, she will now become the face for the Paris-Rome 2015/16 Métiers d'Art collection campaign, which is also being shot by Lagerfeld himself. Stay tuned for the Chanel show, but for now, take a first look at Kristen's starring role in the new film.
