"They are my favorite suits!!! Coming from a girl who has swam competitively her whole life, taught lessons for 5 years and owns like 40 sets, nothing compares to OOS."

“The fit is perfect!! Custom made to fit my body shape/measurements. Sooo soft! My fave swimmies."

Valentina P.

River Reversible Top

"Every bottom from One Ocean Swim is so comfortable to move around in. Every top has just the right amount of support!"

"The custom swimsuit is so worth it! The fabric is a thick swim fabric and the colors are exactly as described online. Though my suit doesn’t have padding in the breasts, I truly didn’t feel like it was necessary. I will be purchasing another in the future!"

“I was searching for more coverage in the bottoms. Most swimsuits make me feel insecure. These swimsuits made my holiday a blast and I never felt uncomfortable or in need to adjust. They are well made and soft. Fit wise they are amazing."
