When it comes to celebrity-loved athleisure, this one(sie) style stands out.

STars like Hailey Bieber, Ariana Grande and Victoria Beckham are taking matching sets a step further this fall with one-piece looks for workouts and lounging alike.

The former Spice Girl went sporty earlier this month, pairing Alo Yoga’s Alosoft Suns Out Onesie ($128) with Nike Air Force 1 sneakers ($90) for an outing on a yacht.

Addison Rae stepped out in the same style — which Alessandra Ambrosio and Kendall Jenner also own — just two days later, dressing it up with a satin Prada headband in Los Angeles.

But the bike short-length style — which is made of Alo’s “velvety soft” fabric and promises light to medium support — is far from the only sporty style stars love.

Hailey Bieber brought a skin-baring element to the trend earlier this month, wearing her Frankies Bikinis Clara Cutout Onesie ($130) to pilates class.

But the second-skin spandex style can also stretch beyond the gym, as Ariana Grande proved with her Girlfriend Collective Earth Cami Unitard ($88), which features leggings on the bottom instead of shorts.

She’s yet to say “thank u, next” to the look, which she owns in two colors and wears on repeat.

And as with most curve-hugging style trends, Kim Kardashian has also rocked a version; earlier this month, she traded her monochrome Balenciaga looks for her own Skims All-In-One Shine Square Neck Tank Onesie ($128), which Kendall Jenner’s also worn.

It’s not the first time the look’s cycled into fashion; spandex rompers also spiked in popularity back in 2019, when Page Six Style tried out the look.

And catsuits were a cold-weather staple last December, with celebrities ringing in the holiday season in skintight fashion. 

Like catsuits, however, there are plenty of ways to layer this onesie look for more everyday ensembles. If you’d rather not go one(sie)-and-done by sporting the style on its own, simply pair it with a blazer, or bundle up with a crewneck or jean jacket.
