A swimsuit line designed to fit like underwear, onewith was founded by Hayley Cannon (Segar). While packing for a trip to Miami, Hayley discovered that she had plenty of swimsuits that looked great on, but felt terrible on her body. She then had a Eureka moment: what if I could make a swimsuit that felt like my favorite underwear?
My onewith swimsuit is more comfortable than other swimsuits I’ve worn. I found it easier to move around in, and when I dove under waves it stayed in place. I’m not sure I would describe it as fitting exactly like underwear, as my suit was a little bigger than I’d have liked (I recommend ordering a size down from your normal size to alleviate this problem). On the plus size, I did feel cute and I received a lot of compliments! I also didn’t need to adjust the suit every five minutes, which was a welcome change from other swimsuits I’ve had. I am tempted now to try one of their one pieces to see how it feels.
