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.

    Perfect seamless fit!

    These bottoms are full coverage, sit perfectly on my body, and don’t dig in at the seams at all! While moving around the suit stays put but doesn’t feel stiff at all!

    Fits so good and material feels divine - def size down

    As a curvy girl who fluctuates between size 14-16 and 16-18

    I read reviews to size down but I was a little nervous bc I usually size up and thought maybe it’ll be fine. Wearing it(2x) dry fit like a glove but not tight on my skin - now usually that would be fine but once I got in the water it expanded a lot ! everytime I swam forward/anyway under water it would just fall and expose my lower tummy. I can’t exchange since I wore it so I ordered another one in XL. I’m hoping it won’t fall as much as the 2x in water but I thought ordering a L was pushing it lol so we shall see . Other than that I really love the material and how it feels on! The most comfortable bikini I’ve ever worn in my life tbh! Boosted my confidence as a curvy girly ily onewith ♡

    Thank you so much for your review and feedback, Stephanie! We're so glad you love the comfortable fit of Hampton! We're sorry to hear your first order turned out to be too big. Please note, our suits require a gooood stretch as directed to help warm up that soft inner grip strip that lines our suits. If your suit did not require a stretch, then that's a sign it's too large to start, and when worn in the water, it will allow for the water to move between your body and the suit, which can lead to it stretching out an undesired amount. We hope you've been loving the size down!

    Perfect

    I’m a small chested big hip girl. I weigh 150lbs, and my normal size in pants is 8 or large. My biggest problem with swimsuits is my hips look like a busted can of biscuits with how the swimsuits are cut. I used to opt for lace up around the hips, but those are hard to come by. This swimsuit is perfect. There is no bulging at the hips, which is a miracle for me.
