After a short season of fashion obligations, Cara Delevingne is back on the film circuit with her new movie, Valerian and the City of a Thousand Planets. In the Luc Besson-helmed science fiction flick, which is slated for July release — making it a frontrunner for this summer's must-see blockbuster — Delevingne plays Laureline, an intergalactic secret agent partnered with Dane DeHaan's Valerian. Five years in the making, the film is an adaptation of a beloved French science fiction comic and will also star the likes of Clive Owen, Ethan Hawke — and Rihanna, playing an alien stripper, as if the rest of it weren't already enough to send you flocking to theaters.

On Monday evening, the promise of a teaser of the sci-fi epic brought an It crowd of models and actors — Delevingne's milieu — to view the new trailer. Kendall Jenner, Lily Donaldson, and Jaden Smith all put in appearances, as did Delevingne and Besson themselves. Delevingne, model-turned-actress, proves once again that while her film career might be taking center stage, she's still a sartorialist at heart.

Who: Cara Delevingne.

When: Monday, March 27.

Where: The trailer screening of Valerian and the City of a Thousand Planets, directed by Luc Besson, in Los Angeles, California.

What: A tweed dress with a matching cropped jacket with leather and zip detailing by Alexandre Vauthier from the Fall 2017 Couture collection.

Why: Though this look was redone for the Fall 2017 ready-to-wear collection with a simplified, but nearly identical, silhouette, it's the asymmetrical cut of Delevingne's look that betrays it for the haute couture creation it is. The look is part of the same lineage as the Chanel that Delevingne has favored lately, with its edgy take on classic tweeds, but with the daring, irreverent touches that have made Vauthier a favorite of Bella Hadid, for example. For a bit of added boldness, Delevingne foregoes the polka-dotted tights with which the look showed both on the couture runway and in the ready-to-wear lookbook. Simple black pumps top the whole thing off, and really, what more do you need when you're already a movie star?
