Why we Stopped Wearing Traditional Swimsuits
When it comes to swimsuits (and clothing in general), comfort shouldn’t be optional. Here’s why we stopped wearing traditional swimsuits... and why you should too!
This story starts when our founder was packing for a trip to Miami and trying on swimsuit after swimsuit, frustrated with the way they made her feel. Tight, bulky seams dug in and squeezed in all the wrong places, making the swimsuits unflattering and just plain uncomfortable.

Even styles marketed as “seamless swimwear” still relied on tight seams and elastic. You can read more about why onewith goes beyond “seamless” here. On this day, she finally said it out loud: “I just want a swimsuit that fits the way my no-show undies do.” Because like so many women, she always felt better in her seamless underwear than she ever did in a traditional or "seamless" swimsuit. That was her lightbulb moment! If she could create a swimsuit that fit the way her favorite no-show undies did, she’d crack the code. So that’s exactly what she did!
From the very first onewith sample, there was no going back. It was the flattering, dig-free, comfortable swimsuit fit she’d been looking for her entire life. One that just laid flat on her body, like a second skin.

So if you hate the way traditional swimwear makes you feel, we think you’re going to love onewith! It’s time to ditch traditional swim and make the switch to our better-than-seamless swimsuits that fit like underwear®. Shop onewith here, and follow along on Instagram for all things swim that fits like undies.
