Looking Back at 2025: A Year of Growth for Swim That Fits Like Undies

2025 was a huge year for our small business! It was filled with launches of new swim that fits like undies styles and colorways, some IRL moments to connect with our community, firsts, and a few pinch-me moments (hi, Shark Tank 👋). Here’s our official 2025 recap, breaking down each month and everything we brought to life along the way.

We started 2025 off with a bang! In January, we launched two new swimsuits that fit like underwear^®, Jennings and Kittery. Jennings would quickly become a best-selling onewith style. The Kittery Classic Triangle Bikini Top is a classic triangle string top, done onewith style with edgeless cups! The Jennings V-Cut High Waisted Bikini Bottom is a high-waisted, high-cut, dipped cheeky style designed by our Instagram followers, and it quickly became one of our best-selling beyond-seamless bikini bottoms to date. We ended the month with a feature on Shark Tank, where we landed a dream deal with not one, but two Sharks! Check out the must-have better-than-seamless swim styles we brought to the tank here. 

Next, in February, we launched our first ever collaboration: the Mari x onewith capsule collection! This drop from the Bachelor + Shark Tank alums was a limited-edition, with 3 of our best-selling swim that fits like no-show undies styles in 2 fun and fresh colorways, thoughtfully crafted by Mari. It featured our Foxon Tie-Front Top and Woodmont Bottom in a vibrant green, Lucky, as well as our best-selling Bellows One Piece in a flirty floral print, Mariposa. 

In April, we sweetened things up for our Hampton, Huntington, and Compo bottoms; they launched in Jelly! It's our beautiful blue raspberry-inspired colorway that is incredibly versatile, making for a great beyond-seamless swimsuit color for the summertime. We then went on to launch more styles of our flattering swim in Jelly by popular demand. 

In May, we launched a new sports bra-inspired bikini top: the Mystic Scoop Neck Bikini Top. Like most styles we launch, we designed Mystic based on feedback we kept hearing: some of you loved the scoop neck, sporty vibe of earlier styles, but wanted a more precise fit—especially under the bust. So we listened! Mystic features a curved underbust that helps prevent gapping, a shorter shelf for a snug-to-you feel, and a tie-back for easy adjustability. It still has that second-skin comfort we’re known for—just with a little more structure where it counts. 

Next, in June, the neutral everyone was begging for had washed ashore! Cove is a taupey brown inspired by the sunlit, rocky inlets and coastal calm of New England. Catch a wave with the mermaids in this stunning, subdued hue of our swim that fits like undies. Available in our 2 best selling styles of swim that fits like undies,  the Westerly Top and Merritt Bottom.

July was a big month for onewith... our utility patent was officially granted after 4.5 years of research, development, testing, stretching, refining (and a lot of waiting)! Patent No. US-12357039-B2. Translation? The magic behind our second-skin swimwear is now protected because it didn’t exist before. We built it from scratch.

In August, we launched Mystic in Jelly, and had our annual team retreat! We rolled out the sweet blue hue across our collection of better than seamless swim earlier in 2025, with Mystic joining the Jelly collection just in time for the end of Summer! Plus, our fully remote team came together for a New England themed team retreat. We gathered on the Connecticut coast (where onewith was created!) for a mix of relaxation, connection, and a little New England magic. 

In September & October, the onewith site got a fresh new look! Our site a glow-up, making it clearer, easier to use, and (of course) fun to browse our collection of swim that fits like undies. Plus, we launched Mystery Bundles again for a very limited time, and they were a huge success. 3 surprise pieces of swim that fits like undies for the price of one? What's not to love?! 

To end the year, onewith turned 4, and launched a very special Anniversary Capsule Collection 🎉 This capsule collection nods to the silhouettes our community already loves, but updates them with fresh details that show just how much onewith has evolved. This celebratory drop includes our second-skin take on a classic tie-sided bikini bottom, a bralette-inspired top—our first-ever sister style to the best-selling Westerly top, complete with an adjustable back—and the highly-anticipated Idlewild One Piece that’s been making waves on Instagram.

And that's a wrap on 2025! Thank you so much for making this year so special for our small biz. We can't wait to show you what's next!
