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.

Top notch customer service
I made an order ahead of a trip. A few days later I realized that my oder contained a “pre-order” item and as a result, the full order would not even ship until after the trip I was buying the items for. I reached out to customer service and they responded super fast, maybe within an hour. I explained the mishap and also let them know that the pre-order alerts/flags were not present in the browser I made my order in, but when I tried in a different browser they were visible. Pearl thanked me for letting them know and gave me a full refund, with no hassle. She even offered to connect me with someone who could help me identify items that would arrive in time for my trip. I can’t speak to the quality of the products as I haven’t tried them yet, but the customer service was really great!

If you ever need style or size guidance, our team is always happy to help.

Still haven’t gotten my refund and my return package was received.
Response from onewith swimJun 25, 2026
Hi Jaime, as we relayed over email, returns are individually inspected, and processing time for returns, once received, is 10 days. Once the refund is initiated, it can take several additional days to appear on your statement depending on your bank. You will also receive an email confirmation as soon as it is processed. ☺️ This is also listed in full in our return/exchange policy on our site. Hope this helps!

DO NOT ORDER FROM THIS COMPANY!
DO NOT ORDER FROM THIS COMPANY!! The swimsuit fit terribly so I returned it over a month ago. The suit is in perfect shape, I did not remove any of the hygiene stickers etc. Customer service is awful, they have been ignoring my dozens of emails about my refund in the past month. They kept saying it’ll be processed by June 21st, June 21st came and went and no refund and no response. Unless you’re 110% sure you’re keeping this product do not order because they will rob you and you will be out $100 after you return the product.
Response from onewith swimJun 22, 2026
Hi Rae, thank you for sharing your feedback. We're sorry to hear the fit wasn't right for you. We do want to clarify the record here: your return was received on June 11, and your refund was processed on June 21, which is exactly within the 10 day window outlined in our return policy. A confirmation was sent to your email that same day. As noted in our correspondence, once a refund is issued, it can take several days to process with your bank. We responded to every email within our 1-3 business day window throughout this process and were in consistent communication with you. We understand waiting for a refund is frustrating, and we're sorry the experience felt that way, but we did not ignore your messages or withhold your refund. The funds have been issued and should be reflected in your bank account shortly if they aren't already.
