Another day, another film festival: The pack of actors making the European festival rounds are setting up camp in Zurich, Switzerland, for the city's annual festival. One such actor is perennial Louis Vuitton favorite Jennifer Connelly, who turned out with co-star Ewan McGregor for the latest premiere of American Pastoral. She traded in a utilitarian scuba dress in San Sebastian for a still-sporty (and still-ruffled) look from the same collection. It must be nice to be a Louis Vuitton girl — she's one of Nicolas Ghesquière's brand ambassadors, having starred in both Spring and Fall campaigns last year, the latter alongside fellow perennial favorite Alicia Vikander. Perks include a wealth of red carpet options, adapted for your pleasure.

Who: Jennifer Connelly.

When: Monday, September 26.

Where: The premiere of American Pastoral at the Zurich Film Festival in Zurich, Switzerland.

What: A custom Louis Vuitton top and skirt adapted from the Resort 2017 collection with mirrored sandals.

Why: Connelly's last great Louis Vuitton look combined utilitarian scuba with a pretty edge, and here, she's trading in her beachwear for land sports. A track shorts and ruffled crop top on the runway transforms into a slit skirt and elegant white tee without losing the sporty edge that threaded the whole Resort 2017 collection together. A slicked-back updo lets the look speak for itself, and it also doubles down on the athletic aesthetic she's cultivating throughout this press tour. Like her best look at San Sebastian, this one toes the line between sportwear and more conventional red carpet attire by combining the best of both. It has a hint of subversion — a floor-length skirt, punctuated by a bold, racing-stripe red panel, with a more delicate and classically feminine top. If you're Jennifer Connelly, the choice between a formal look and a low-key athleisure look is no choice at all.
