    This onesie is everything. First of all, I've been teaching Pilates for over 10 years so I've seen a onesie or two, and this is it. Many brands dont have built in bras with padding, but this one does- so essential! The print is beautiful, so pretty for fall. The first day I wore it my husband was stunned, its his new favorite outfit of mine now. Its very slimming and flattering, the cutout in the back is the right amount of show of skin without it being too much. I taught a Pilates class the first day wearing it and got so many compliments. I took a walk as well afterwards the same day and was stopped twice to ask about it- its just a very pretty outfit. Ive worked out in it as well (Pilates, Yoga, and walking a ton of steps in Disney World) and no complaints. For reference I am 5'9", athletic build with a long torso and broad shoulders so when I order onesies I usually size up. So I did an XL, but I believe the brand is definitely true to size and the sizing chart was very helpful and on point (I measured before ordering and it was good!). Will be ordering more things and cant wait!

    I got the rhapsody color in medium and it fits true-to-size (5'5", waist 28.75", hips 39", thighs 22.75", athletic build). The fit is flattering, and I got a bunch of compliments on it. I wore it surfing a couple times, and it works well as like a rash guard, but a few gripes. 1 - it doesn't have a key loop. 2 - the built in bust is too small and not supportive enough for larger chests (I'm a 34DD). 3 - I'm afraid the straps will slip while surfing, but they're fine for less rigorous activities lol. Maybe the strap issue will be less of an issue for smaller chested girlies. I'm not sure how often I'll actually use it for surfing, but I'm sure it'd make a great salsa dancing, yoga, etc. outfit, too 💃. Overall, I'm happy with it.

The story behind it

The story behind it

One piece. Built for the way you move.

I wanted activewear that didn't just function — I wanted it to look as good as it felt. So I made the Antao: the full-length sister to our best-selling Paros. Buttery-soft fabric that moves with you, built-in support, full-length coverage. Made for strong pilates classes, hot yoga flows, coastal beach runs. The one I reach for when I want to feel strong AND put together. <3 Kels
