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) 🫧
I have told everyone I know about this brand! Love it!

It's wonderful supporters like you who help us grow our community of happy customers, and we couldn't be more grateful for your kind words and recommendation! 🌊
Fits well, adjustable for rib size bc the tie front!❤️
Thank you so much for your review, Jodie! The Westerly is definitely a fan (and team!) favorite, thanks to its adjustable tie front! We're so glad you love it too :)
I first found this brand a few years ago on TikTok and everything they said about wanting a suit that fits like your favorite no show panties was exactly what I had been searching for. I have 3 different suits and just ordered another. Pro tip: if you have a booty and want more back coverage, I ordered a size bigger than needed and did a ladder stitch on the waist in the back
Thank you so much for your incredible review, CM! We're absolutely thrilled to hear that you've been loving your onewith suits and that they provide the swim-that-fits-like-undies fit you've been searching for! It truly means the world to us that you've come back for multiple suits over the years - that's the greatest compliment we could receive. We love your creative approach with the ladder stitch modification to achieve your perfect desired coverage. Your continued support and trust in our brand means everything to us, and we're so happy you've found your perfect swim pieces with us! 🌊
True to size and when stretched, fit perfectly! I love these bottoms and will be purchasing more in the future!
Thank you so much for your review, Olivia! We're so glad to hear you were able to achieve a truly second-skin swimsuit fit after giving your suit a stretch. We look forward to having you back in the future!
