product details
  • designed in USA, made in China
  • patent-pending
  • LATEX INFO: we cannot guarantee that the inner grip strip of our suits is entirely free of latex. If you have a latex sensitivity or allergy, we recommend exercising the same caution you would typically use when assessing whether to wear a product that may contain latex.
  • 80% nylon, 20% elastane
  • hand wash only, lay flat to dry
swimsuit care
  • Hand wash in cold water as soon as you can after use (rinsing in the shower is fine!)
  • DO NOT machine wash.
  • Lay flat to dry, do not hang.
  • Do not dry clean, iron, or machine dry (even on a delicate cycle...) as this can, and most likely will, damage your onewith.
  • Hot tubs and chlorinated pools with harsh chemicals can impact the quality and longevity of any swimwear, so it’s best to avoid them if you want to keep your swim in tip-top shape.
  • If you wear your onewith under normal clothes, keep in mind that friction can create pilling/snagging. We prefer to wear our onewith under beach cover-ups/sarongs, which are created to be worn with swim.
  • Sunless tanners, suntan lotions, oils, and harsh chemicals can ruin your onewith - ensure to not get these products in contact with any swim/garments!

  • onewith = 2 layers of normal swimwear fabric, just like any other swimwear. people tend to think our swim is either 1 layer of fabric, and/or super thin, like no-show undies. that is not true! again, our swim has 2 layers of fabric. It's just bonded together, not sewn with tight seams, which gives it a sleeker appearance that people may read as "thin." While we can't guarantee our suits are frontal-wedgie-free, so-to-speak as every person's anatomy is different, we can say that there is no reason why our suits would cause 🐪toe more than any other swimwear.

  • yes, all of our bikini tops + one pieces have removable bust cups that you can leave in, or take out!

  • we get it, the itch to get your swim that doesn't dig in ASAP is real! luckily, we do offer an Express shipping option if you do need it ASAP. otherwise, we offer free standard shipping on US orders over $85. all orders with standard shipping ship from our Connecticut, USA warehouse within 2-5 business days of receiving your order.

  • ALL onewith suits feature our inner grip strip, which keeps the suits secure without the use of tight seams or elastic that digs. the inner grip strip is super soft and flexible.

    SO FLATTERING!

    I’ll admit, I was skeptical… but they honestly fit even better than seamless underwear. I’m one who was never able to wear a bikini bottom due to how it pushed my stomach out but now I can confidently say I will be wearing these all summer!!! Thank you onewith!!!

    Thank you so much for your review, Stephanay! Nobody should ever feel like a sausage in a casing, and we're SO glad the Compo does the opposite, providing a comfortable, ultra-flattering fit. Enjoy your dig-free swim 🌊
