For most artists, a canvas is static. It hangs on a wall, fixed in place, an interaction with the world that is limited to light and the viewer’s gaze. For Onewith, the canvas moves, shaped by the body, water and motion.
That idea comes to life with the launch of the Onewith x Claire Buckley capsule collection. While the collaboration introduces original artwork by Brooklyn-based painter Claire Buckley, it’s ultimately a reflection of Onewith’s deeper innovation: patented swimwear construction that has quietly rewritten what swimwear can feel like and, increasingly, what it can become.
Founded by Hayley Segar, Onewith was born out of a moment of frustration familiar to countless women. A lifelong beachgoer who loved fashion but hated swimwear, Segar found herself on her apartment floor in 2019 after yet another disappointing try-on session. After trying on swimsuit after swimsuit—all of them digging, compressing or riding up—she blurted out, “I just want a swimsuit that fits like my no-show underwear,” an offhand comment that became the brand’s north star.
What followed were years of development and a first-of-its-kind approach to swimwear construction—no digging, squeezing or compressing. That comfort-first engineering has always been the brand’s foundation. But with the Claire Buckley collaboration, it becomes something more: proof that Onewith’s technology unlocks new creative possibilities.
Traditional swimwear relies on seams and compression to create structure, often breaking up prints and distorting patterns. Onewith’s patented construction uses bonded, raw-cut edges that lie flat against your skin, without the discomfort of bulky seams, rigid elastic or harsh compression. The suit conforms to your body, creating a personalized, ultrasmooth fit that stays in place without digging in.
The partnership itself is deeply personal for Segar. Long before the idea of a collaboration emerged, she was a devoted admirer and collector of Buckley’s work, living with the artist’s paintings on her walls and feeling a rare emotional connection to them. During a visit to Buckley’s studio to pick up her second piece, Segar decided to ask whether the artist would ever consider collaborating. Together, they brought Wonderwave to life, an exclusive artwork created for Onewith that blends prism and pastel, striking yet soft.
The exclusive artwork is printed across three of Onewith’s signature silhouettes—the Westerly tie-front bikini top, the Jennings V-cut high-waisted bikini bottom and the Bellows plunge high-cut one-piece.
This capability speaks directly to Onewith’s broader mission to change swimwear so women don’t feel the need to change themselves. From the beginning, the brand has rejected the idea that discomfort is the price of looking good. Instead, it has prioritized how women actually want to feel in a swimsuit: confident, comfortable and unrestricted. Every piece is size inclusive (XXS to 3XL) and built with both real-world testing and empathetic design. No pinching. No pulling. Just a better experience in and out of the water.
That philosophy has resonated widely. Since launching in 2021, Onewith has built a devoted following and gone viral multiple times for its “feels like underwear” fit. The brand’s momentum reached a pivotal point with its appearance on ABC’s “Shark Tank,” a defining moment that helped propel Onewith from a founder-led passion project into a fast-growing, design-driven swimwear business. Just as importantly, the milestone arrived after years of product development and early traction, reinforcing that the brand’s success was not overnight but earned.
That evolution is further underscored by Onewith’s four-year brand anniversary, showcasing how far the business has come both before and after “Shark Tank.” The Claire Buckley collaboration reflects that maturity, signaling a brand confident enough in its technology to use it as a launchpad for creativity.
In a swimwear market long dominated by trend cycles and aesthetic sameness, Onewith is proving that true innovation starts beneath the surface. Sometimes, when comfort comes first, it creates space for something unexpected: art that moves, lives and feels as good as it looks.
