I don’t know if it’s just my FYP, but it looks like the return of ‘80s Jane Fonda-esque workout ‘fits is in full swing. One style that’s making a particularly big come-back is unitards. Bodysuits, onesies, crotch monsters — whatever you’d like to call them — are slowly taking over the activewear space with brands like Lululemon, Estroni, Glassons, Girlfriend Collective, STAX and more bringing out a bunch of modern cuts and colourways.

I know what you’re thinking, working out in a unitard surely runs the risk of camel toes, wedgies, sheer squats and more. However, these aren’t just your regular cotton onesies, they’ve been designed specifically to be activewear. Think thick, moisture-wicking fabrics, supportive cuts and smooth silhouettes.

After trying out a unitard for myself (I’ve got Estroni’s Tank Bodysuit), I’ve decided that it’s like your favourite crop and shorts (or coziest leggings) had a baby. They’re comfy enough for all-day wear (#grossgirlsunite), there isn’t a restrictive waistband crushing your tummy after every meal, and they layer in ways two pieces could never.

Of course, this particular trend isn’t going to be for everyone — it feels very “tell me you grew up doing ballet without telling me you grew up doing ballet”. But if you’re keen to give it a try, here’s where you can buy activewear onesies/unitards.

Estroni Tank Bodysuit

Estroni Tank Bodysuit, $109

We’re obsessed with pairing these simple, but sleek activewear bodysuits with chunky sneakers and socks. You can wear them to the studio, on your weekend walks and even to brunch — who are we kidding, especially to brunch. Plus, right now, if you use the code ‘WELOVEPTV’ you can score 10% off sitewide.
