“Ok cool, you launched your Huntington thong bikini bottom…but I really only wear HIGH WAISTED thongs. When are you coming out with that?” 

We hear you, and we raise you: Penfield.

A dipped high-waist front with a Brazilian-cut back. It’s almost *too* good, and really hits our ‘swimsuits that feel like underwear’ concept home. onewith’s inner grip tape at the top edge and along the legline holds Penfield in place, while our elastic-free and better-than-seamless swimwear bonding ensures that nothing pinches or squeezes, for totally dig-free swimwear look that is beyonddd cheeky.   

To balance out Penfield’s booty-loving back, we love pairing Penfield with our Thames Scoop Neck Bikini Top, which has more coverage in the back. 

📏 fit note: if you’re not sure which size is best for you, check your measurements against our size chart here. And if you end up between sizes, we recommend you size down for this style.

    My 🍑 has never looked better

    These are my favorite bottoms, hands down! I love the Buzzin color and these bottoms hit in the right places to make my butt look the best it’s even been.

    This is my second swimsuit from OneWith and I immediately ordered the mystery bundle so now I have several sets and an extra non-thong bottom for ~family events~ Every suit is perfect, doesn’t dig and looks like it was custom made for me. After experiencing OneWith I don’t think I could ever wear another swim brand!

    FINALLY a thong bikini for my body

    I think I will buy these bottoms and these bottoms alone for the rest of my life. I struggle so hard to find bottoms in the style/coverage that I want that are also flattering to my body. As a “mid-size” girl (5’9” 200lb, lean with some extra squish around my tum and bum) I constantly feel forced to choose between teeny tiny bottoms that barely cover my hoohah or ones that cover me up past my belly button and look like a diaper. When I do find a mid-belly high waist option, it’s always full coverage on the bum. So FINALLY I found the perfect style - not to mention the “fits like underwear” fit is sooooo flattering. I feel confident showing off my bod more than ever in these bottoms. PLEASE RELEASE MORE COLORS! esp dark ones and patterns, the light ones scare me a little. Thank you onewith!

    Amazing fit! Even better look!

    I own two pairs of bottoms from onewith and I can honestly say the quality and fit are EXACTLY what I’ve been looking for. I love the look of these as well. As someone who’s aesthetic is entirely minimalist and modern, onewith fits the bill for a classy, modern, and simple fit and design without all the extra frills. No need to oversell when your products are this good!!

    Great for lounging not so much for playing

    I’ve bought a few of these bottoms, different cuts different colors, now and the general feeling I’ve had with them is they look great super beautiful make me feel great! However do not wear them doing water sports or down water slides, I found out the hard way.
