Why the Unitard Is the Ideal Workout Wardrobe Staple

The workout unitard, however eyebrow raising it once was, is officially back in style with growing popularity that is both celebrity and It girl approved. The one-piece’s recent rise to fame makes sense, especially given that its backing comes from none other than Kim Kardashian, who has worn the all-in-one outfit beyond just the gym. On the runway, many designers from Saint Laurent to Marine Serre have explored the “unitards, but make it fashion” idea. But however fashion-forward the unitard has recently become, at its core it is a tried-and-true workout wardrobe staple with more functionality than its counterpart, the exercise dress. Whether cropped, full length, or long-sleeve, workout unitards are sweat wicking enough for any high-intensity workout class yet still stylish for any post-workout plans. With fall fashion on our minds, styling a workout unitard is more straightforward than you might think. See it as one of your go-to layering pieces and throw a crisp, oversized button-up over and pair it with the season’s best sneakers.

Also known as a playsuit, onesie, workout romper, or bodysuit, this athleisure style combines the best of bike shorts with all-in-one ease. Colorful full-length unitards from Girlfriend Collective and Free People are ideal for lower-impact workouts like Pilates, yoga, or barre. A pair of matching grip socks will complete the look. For those looking to break a serious sweat, Outdoor Voices’ technical, quick-drying fabric allows for a seamless transition from work to play. Workout unitards from hero brands like Nike and Adidas are always a hit, while onesies from newer labels like Héros, Nagnata, and Year of Ours are also ones to consider. We’d be remiss not to mention the influence TikTok has had on the unitard’s popularity, with styles from Alo Yoga, Beyond Yoga, and Aritzia struggling to stay on shelves for long.
