✨ what to know when your onewith arrives! ✨

onewith is designed to fit like your favorite seamless undies — and that starts with a little warm-up. 💫

you want your swim to feel snug right out of the package — that’s a good sign! your onewith swim actually should dig in a bit to start. then, after giving them a bit of a stretch, your suit will be second-skin perfection, just like no-show undies!

this is what your suit SHOULD look like when you first put it on. it should still dig in a little at first. ✅ ✅ ✅
