19 best unitards and one-pieces for a stylish workout session

You've probably already spotted British activewear brand Adanola on your Instagram feed – we've spied its logo-embroidered tracksuit sets on pretty much every influencer out there. This strappy unitard is crafted from a nylon-spandex blend for a supportive close-fit and is now our go-to uniform for yoga and Pilates.

Who knew LA cool-girl brand Reformation also did hella cute activewear? We love the on-trend square neckline and flattering scoop back on this short unitard. Although the bodice is double lined it doesn't have built in cups, so we advise layering with a sports bra for high-impact workouts.

If you're looking for a hella cool unitard on a budget, you need to check out H&M's new activewear collection ASAP. Our favourite pick from the latest drop is this wet-suit style black jumpsuit. Crafted from the brand's unique DryMove fabric, this baby has sweat-wicking properties that will keep you feeling dry and fresh post gym session. It's also available in a chic muted green.

We're in love with the berry hue on this ribbed unitard from Free People's activewear line FP Movement. While we don't recommend wearing this number for hardcore gym sessions and sweaty runs, it will work perfectly for yoga and barre classes.

Spanish brand Desigual's floral print unitard is bound to get you noticed. Yet, the brand has not sacrificed functionality for style; the design is crafted in sweat-wicking polyester and blended with elastane for a close-body fit. Prepare to be the best dressed in your spin class.

Gilly Hicks’ ruched unitard is so versatile. Wear it solo during sports, layered with a cardigan, or underneath oversized sweaters to create the look of running leggings.

Lululemon’s unitard is expertly cut from the brand’s lightweight Nulu fabric to ensure a smooth silhouette and unrestricted movement – these babies won’t dig in one bit, or leave unsightly red marks on your skin. Plus, this style has a built in bra (and removable cups) for that extra touch of support.

If bright prints aren’t for you, play it safe and stick to versatile neutrals like marl grey. We love Year of Ours’ glam-yet-functional, stretch jersey unitard. Check out the tape branding across the waist and the flattering scoop neckline.

Live The Process’ cut-out unitard is cleverly designed to look like a two-piece set. So, if you love the look of a bra top and leggings but not the fuss (why do cropped hemlines always ride up during runs?) you should add this to your basket. Plus the low back is perfect for showing off those upper body gains.

Even though we love a bit of coverage, short unitards are better for barre and yoga practice: a bit of skin-on-skin grip is ideal when perfecting your pliés and tree pose. We like the adjustable strappy back and versatile black shade of this Sweaty Betty number.

You can always trust ASOS to come through with new, innovative activewear from up and coming brands. This pink unitard – from lifestyle brand VAI21 – has a low scoop back with unique strappy detailing, that is far too good to hide at the gym – it’d definitely double as a summer festival look.

A new Women’s Health favourite, Vuori’s designs are inspired by coastal California – so expect to see cool tennis dresses and co-ords that suit both sport and play. This unitard is no different. It has an in-built sports bra for running but looks great styled with a cardi for brunch with pals.

The Girlfriend Collective is spearheading the sustainable sportswear revolution: all of the brand’s fabrics are partially made from recycled plastic waste. What’s more, the sizing is super inclusive too (XXS to XXXL). Two big ticks from us.

Editor favourite Year of Ours’ unitard is one for the yogis out there – super-soft, stretchy and complete with sculpting panels on the bodice.

Nike's ribbed unitard is dyed in a bold pink and purple hue and finished with supportive thick straps and an on-trend square neckline. Wear this one for yoga and pilates.

Nike's beautiful unitard is a wardrobe must-have. And not just for the gym kit side of things: the sweeping V-neckline and slender cross-back straps make it ideal partywear – just add heels and a blazer.

Cult swimwear brand Alexandra Miro has just launched activewear and we couldn't be more excited. Inspired by '90s resort campaigns, this black unitard is trimmed in contrasting white and cinched with a retro circle belt. Detach the straps to wear it as a bandeau once your LISS workout is over.

Ernest Leoty’s couture roots means the brand makes pieces with your body in mind: this unitard is expertly seamed and darted to flatter and elongate your figure. Throw in that elegant taupe and white palette, plus the slim spaghetti straps, and you’ve got the perfect outfit flex for your next barre class.

If you are daunted by bodycon fits then Kim Kardashian’s shapewear brand, Skims, is one to consider. One for light stretching or lounging, this ribbed unitard is lined with the brand's signature power mesh to smooth and shape your figure. It's easy to find your perfect fit too, thanks to the brand's wide size range – we're talking XXS to 4X, people.
