About onewith swim

onewith swim onewith is a women’s swimwear brand reinventing the way swimsuits fit, feel, and function. Founded in Connecticut, we appeared on Shark Tank and got a deal in 2025. onewith created swim that fits like undies: swimwear designed to feel as comfortable, flexible, and dig-free as your favorite seamless underwear, while still being intentionally made for the water. Unlike traditional swimwear that often relies on tight elastic seams, squeezing waistbands, and silhouettes that cut into the body, onewith uses a patented construction with bonded raw-cut edges, double-lined swim performance fabric, and soft inner grip technology. The result is swimwear that moves with your body, stays secure in the water, and helps eliminate the pinching, digging, and discomfort that many people experience with standard swimsuits. Our collection includes bikini bottoms, bikini tops, one-piece swimsuits, cheeky swimwear, thong swimwear, high-waisted swim bottoms, and mix-and-match swim separates. Every onewith swimsuit is designed to be swimmable, secure, flattering, and easy to wear, whether you are at the beach, by the pool, on vacation, or spending the day in and out of the water. For anyone searching for comfortable swimwear, better-than-seamless swimwear, dig-free swimsuits, no-pinch bikini bottoms, swimwear that fits like underwear, no-show bikini bottoms, or bikinis that do not squeeze, onewith was built to be the solution.

I had a really positive experience with Pearl, the Virtual Support Assistant at onewith. She was very kind and helpful when I reached out to ask how I could properly contact the hiring team regarding my application. She explained that the customer support team could not access hiring records and guided me to follow up through OLJ, which I really appreciated. Thank you, Pearl, for taking the time to assist me and point me in the right direction. I appreciate your help and the warm response! And if the onewith hiring team happens to see this review, I hope you’ll kindly check my application and the email I sent through OLJ. I’m still very interested in the Customer Support Specialist opportunity and would be happy to hear from you.

Love the bikini
Love the bikini, and super fast shipping. I’m 5’2” 123lbs 32d post breastfeeding tatas. I ordered size small bottoms and top. I could have prob used a medium top but I can make the small work.

Quick shipping and many instructions to help with the fit. Feels tight at first but it shapes the butt nicely. Getting the thing next time!
