Have you heard the news? Who What Wear just turned 20, and we invited a bunch of our stylish friends to celebrate. At the iconic Chateau Marmont overlooking Sunset Boulevard in Los Angeles, we partied with Iris Law and Whitney Peak, the cover stars of our first-ever print edition. They mingled with Emily Bader, Maddie Ziegler, Dylan Efron, Owen Thiele, Olandria, Benito Skinner, Connor Wood, Charlotte Lawrence, Ashley Tisdale, Jackie Tohn, Sami Miró, Vinnie Hacker, and many other well-dressed celebs.

Let me set the scene for you. When they weren’t sipping espresso martinis supplied by Movado or taking bites of our Who What Wear–branded cake, guests gamely answered early 2000s–themed questions, made funny faces in our Movado photo booth, took Polaroids, spritzed Donna Karan Cashmere Mist in the bathroom, and danced to throwback songs curated by our DJ for the night, Este Haim.

Eagle-eyed fashion lovers might have noticed some of the evening’s best dressed attendees wore Movado watches, including Kat Collings Wolf, Eliza Huber, Soukeyna Diouf, and Miró. Scroll down to see their outfits, plus everyone else’s. You only turn 20 once, so we made sure to celebrate in style.
