Photographed en route to a yoga class, she was in an outfit that so many of her coworkers have donned in recent weeks. In fact, the three key pieces in the model's off-duty look are basically the most popular clothes in Hollywood right now. Gerber was in none other than the celeb-favorite FP Movement Hit The Slope Fleece, a pair of Ugg boots, and Alo Yoga's 7/8 Airlift Leggings. Supermodels, including Hailey Bieber, have been wearing that Free People fleece practically nonstop. Fashion editors love the comfy jacket, too — and it's selling out fast, FYI. And the buzz around Uggs has been growing louder each year, so we don't anticipate an investment in them going south anytime soon. The shearling-lined boots are designed to be worn year-round, but as expected, they're a cold-weather favorite. Gigi Hadid, Elsa Hosk, Kendall Jenner, Selena Gomez, and Hilary Duff are all fans of the 2000s hallmark come cool temperatures. Last but certainly not least come the leggings. Gerber's ultra-flattering sculpting leggings are from Alo, the unofficial leggings brand to the stars. Jennifer Garner is a big-time fan, as is Jenner, who wears the workout bottoms so frequently. And who can blame her? They really are that good, at least in my experience. Shop the fleece, the Uggs, and the leggings Gerber wore to recreate this supermodel uniform for yourself.
