5 Reasons Women Who Hate Swimsuits are Obsessed with onewith

we didn't set out to make prettier swim. we set out to make swim that feels like the one thing you already feel good in: your favorite pair of no-show undies. no elastic. no edges. no seams digging in or cutting into your shape. below is exactly what changes when your swimsuit is built that way.

1. it doesn't dig in. anywhere.

the band pressing into your hip. the leg opening cutting a line across your thigh. the red marks an hour after you take it off. that's elastic holding the suit on by gripping you tighter than your skin wants. onewith has no elastic in the edges. bonded construction and a soft inner grip strip hold the suit without holding you.

2. you stop adjusting.

the edges don't roll, the bottoms don't creep up when you stand, and the top stays put when you get out of the water. onewith holds through a bonded edge and a soft grip strip instead of squeezing, so there's nothing to tug at.

3. it's the most flattering thing you'll ever put on.

flattering isn't about hiding anything, it's about not creating something that wasn't there. a sewn elastic edge presses in and pushes the skin around it out, manufacturing a line on every body it touches. onewith has no edge to press, so there's no line to see.

4. you forget you're wearing it.

buttery is the word customers keep using and we've stopped trying to improve on it. soft, matte, and it warms to your body instead of sitting on top of it. wet is where most swim turns heavy and stiff, and this doesn't. it feels the same going in as it does coming out.

5. built by a woman who hated every suit she owned

we started with a pile of suits on a hotel floor in 2019 that all had the same problem, then spent two years bonding an edge that stays put without squeezing. since 2021: forbes, instyle, two shark tank deals, one us patent, 50,000+ customers. seamless swim still uses elastic. we don't.
