About Hayley Segar:

Hayley Segar always loved fashion, but hated swimwear. Nothing ever fit right. Until one day in 2019, after a frustrating try-on session, she said out loud: “I just want a swimsuit that fits like my favorite no-show underwear.” That lightbulb moment sparked Onewith Swim.

Launched in 2021, Onewith created swimwear designed to fit like seamless underwear: dig-free, elastic-free, and edgeless. It’s gone viral for solving a problem most women didn’t think could be solved, and in 2025, Hayley brought the brand to Shark Tank, landing a deal with Barbara Corcoran and Jamie Kern Lima.
