Happy birthday, Cara Delevingne! The British model and Vogue cover star celebrated her 32nd birthday last night. The star rang in the milestone by hosting a private bash at the Chateau Marmont in Los Angeles, and while it was a low key affair, the guest list was anything but. An A-list crowd turned out for the celebration, including cameos from Margot Robbie, Selena Gomez, Colman Domingo, Paris Hilton, and many more. (Clearly, Delevingne is popular in Hollywood.)

While the birthday girl herself entered the party via a private entrance (see: the invasive paparazzi car shot below), plenty of celebrities opted for the obligatory splashy party walk-in—photographers and all. Better yet, many stars brought chic party looks for the outing. Take Margot Robbie, who looked classic in her black and white ensemble; The star paired a silky tank top with high-waisted tuxedo trousers, accessorizing with a pair of sky-high platforms. Selena Gomez also went the timeless route, sporting a black skirt suit with Christian Louboutin slingbacks. Kaia Gerber wore an oversized navy suit, while her ex Jacob Elordi chose a demure black look as well.

Perhaps the dress code for the soirée was Hollywood glamour, because all of the notable guests looked red carpet-ready. Colman Domingo sported a dapper black suit with a white dress shirt and tie. (Bonus points for his jaunty little chapeau.) A few attendees, however, did take a risk. Julia Fox rolled up in some sport Willy Chavarria x Adidas pieces, while Paris Jackson went pantless by wearing a crisp white shirt as a dress—complete with the tie. It was a Hollywood bash, after all—a little grungy messiness is a nice ode to the messy Y2K party L.A. scene.
