Formula 1 Halloween Costume Edit, Curated by SI Swimsuit’s Fashion Editors

Halloween is just over a week away, and if you haven’t decided on a costume yet, don’t worry! There’s still time. When it comes to putting together a cute and creative ensemble for your festivities surrounding the holiday on Oct. 31, we’ve got your back.
We love a themed look here at SI Swimsuit, particularly one that speaks to a current cultural moment. And if there’s a sporty tie-in? Even better. With the U.S. Grand Prix at the Circuit of the Americas in Austin this weekend, there’s no more timely costume than a Formula 1 superfan.
Below, SI Swimsuit’s fashion team has curated three different looks that will make for a truly spectacular Halloween costume this season. Plus, each outfit features elements that you’ll certainly rewear all year long—think leather jackets, cool motorcycle boots and staples like tank tops and sunnies—so you’ll get some extra mileage out of your investment.
