The year may have only just begun, but I’m already sensing a theme when it comes to 2026’s biggest style trends: nostalgia. From ‘90s dad sneakers to aughts-inspired snakeskin to beauty looks plucked from 2016, the fashion and beauty zeitgeist has been moving forward by looking back—and, apparently, that includes gymwear. Sleek, minimalist workout sets had their moment. But you might want to start shoving them to the back of your drawer in favor of fun separates that seem straight out of a 2000s workout video (paging Billy Blanks).
According to my TikTok and Instagram feeds, the 2000s athleisure aesthetic is making a comeback, and as an Ed Hardy-collecting, Juicy Couture tracksuit-wearing millennial, I’ve been ready. The vibe is the opposite of the muted Pilates Princess look—think bright colors, big logos, layered tanks and sporty stripes. Even the yoga mom favorite, foldover flares, are cool again.
