Kaia Gerber has always been on trend. When the cool girls gave up their Adidas Sambas in favor of the new It sneakers, the Onitsuka Tiger Mexico 66, Gerber followed suit. She immediately embraced the innovative "skirt over pants" style. This model endorses the revival of the timeless ballet flat. And now she is cooking up a copyable costume formula that includes rehearsal shoes and sweatpants.

You heard it first: ballet flats and sweatpants are the new midsummer trend. Gerber was photographed on Monday, July 8, in her typical laid-back, off-duty look, a casual yet prestigious sense of style. She strutted down the sidewalk in a white tank top with cami, low-rise, loose-fitting black sweatpants, and classic leather ballet flats by Repetto. She accessorized with her usual Thistles sunglasses, a chocolate brown leather shoulder bag, and tangled wire earbuds. (Her trusty silver AirPod Max headphones must be charging at home.)

Kaia's black Repetto BB ballerina flat shoes are a staple in her summer wardrobe. She styles them with pants, wide-leg jeans, and mini dresses. Sweatpants were the next logical style step. But Gerber is not the first to dress up as a ballerina before rehearsal. Track pants and ballet shoes were an unexpected combination that went viral in the spring. Chloë Sevigny wore navy blue Adidas track pants, a matching Ralph Lauren polo shirt, and bright white Maison Margiela Tabi Shoes. (Speaking of heel/flat shoe hybrids, Sarah Jessica Parker was spotted wearing a cross between a kitten heel, a ballet shoe, and a Mary Jane just the other week.)

Going further back in time, the trend can be traced to model Bella Hadid, who decided to interpret the "ballet-core" phenomenon literally, the ultimate fashion catalyst: in 2022, she wore a gray sweatshirt, matching flared sweatpants, and actual light pink satin ballet shoes.
