Reviews Summary

The community says this onesie is incredibly comfortable and flattering, with a supportive built-in bra and secure fit that stays put through swimming, yoga, and active movement. The material feels like soft swimsuit fabric—thick, quick-drying, and sand-resistant. Many appreciate the full coverage and versatile design for both water sports and everyday wear. Most find sizing runs true, though some suggest sizing up for comfort. A few note minor issues with strap fit or back gaping after wear.

I am a onesie convert now
I wasn't sure I was going to love this, especially needing to take the whole top off to pee, but it is so worth it. The fit and material are perfect, I feel like a yoga fairy wearing it. I am 5'4", 112lb, athletic build, the S fit perfectly. Material isn't buttery soft like Beyond Yoga, feels more like a swimsuit, but I like that sand totally slips off of it and it's super comfortable for yoga and lounging around. I went commando in it and nothing was riding up into any lady parts :D

Even with a long torso, I love it!
I sized up for comfort and glad I did because I have a long torso and I’m 5’ 8”. I love the print and got SO many compliments when I wore it! It’s comfortable and stays put through tons of activity and movement.

Perfect
This is the perfect swimsuit for chasing my active kiddos! Love the length of the shorts and cute back details. I always get compliments when I wear it and it's perfect doing yard work on a hot day too :) I'm 5'2" with a petite frame and the XS fit perfectly.

The story behind it

Designed for your everyday. Studio to sea.

I wanted activewear that didn't make me choose - supportive enough for pilates, cute enough for the cafe, sturdy enough to swim in. So I built it. Buttery-soft fabric, built-in sports bra with removable padding. Wear it to the beach for a swim or for your morning flow. The one I throw on for everything. <3 Kels

Got Questions?

Frequently Asked

Is it supportive enough without a bra?

100%. The built-in sports bra with removable padding gives you proper hold — tested through hot yoga, reformer, and pilates classes. The open back with supportive band keeps everything locked in, no extra layers needed.

What if my size is wrong?

No stress — we offer fast and easy 14-day returns and 30-day exchanges. Just make sure the suit is unworn with tags attached. Most customers find the Palme runs true to size.

Can I actually swim in it?

Absolutely! The Paros is designed for water as much as land — wear it for ocean swims, pool days, or in the surf. Just give it a cold rinse after chlorine or salt water and hang dry, and it'll keep its shape.

Will it dig in or ride up?

No digging, no riding. The 4.5" inseam is designed to move with you, the seamless front means zero pressure on your stomach, and the supportive back band sits flat. Buttery-soft fabric that feels like a second skin.

How long does shipping take?

US standard shipping takes 2–8 business days, express is 1–3 days. Orders over $150 USD ship free. International shipping is available worldwide.
