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.
this is swimwear unlike anything else on the market, so with that, it has some special instructions to truly get a fit that's onewith your body ✨ 'warming up your onewith’ (aka giving the garment a stretch) is MISSION-CRITICAL to the fits-like-undies vibe. your swim actually SHOULD dig in a bit to start if it’s your proper size. then, with a stretch at the openings, it should fit and feel smooth, like a second skin (and/or your fave seamless undies) 🫧
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!
Victoria, thank you so much for your review! We're so glad you're loving the beyond seamless fit and feel of Hampton, and that it hugs you in all the right places for an ultra-flattering look. Enjoy your onewith!
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!
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.
We're so glad you found us, Jill! Sounds like Hampton is your perfect onewith fit, dig-free and oh-so-smooth! Thank you so much for this kind review. Enjoy your onewith!
They fit perfectly, wire them to a 9 hour lake day wasn’t uncomfortable at all
That's what we like to hear! We're so glad your Hampton stayed in place and was comfortable for a lake day! Thank you so much for this review, Erin :)
