Look, Olivia Newton-John was a great Sandy Olsson in the movie Grease. No one could forget her rocking out in leather pants and an off-the-shoulder top at the carnival with Danny Zuko. But when Gigi Hadid walked the red carpet at Heidi Klum's annual Halloween party in 2015, the movie version of Sandy slipped our minds.
Gigi's flawless ensemble was put together by Monica Rose, the Kardashians' go-to stylist, and she pulled it off with ease. Wearing nylon high-waisted spandex from American Apparel, a crop top with a sheer panel from House of CB, and a lace-up leather jacket by Caroline Blomst, the supermodel attracted all eyes — even when standing next to Heidi or, erm, Jessica Rabbit herself!
Oh, and those striking red cutout heels that match Gigi's bright lip? They're by Louis Vuitton. Read on to see her gorgeous costume from every angle, which will remind you why you're hopelessly devoted to Gigi's killer style, then shop the pieces you need to re-create her memorable look.
