onewith is proud to be donating 5% of proceeds from purchases of our Core Collection bikini tops + one pieces to The Get In Touch Foundation between 5/22-6/22/24. We are thrilled to be sharing the mission of accessible breast health information through our swimsuits that fit like underwear®️

The Harkness Strapless Bandeau Bikini Top is truly one of our most flattering, better-than-seamless swimwear styles. Why? It’s totally edgeless! Thanks to our patent-pending bonded construction and soft inner grip strip, this strapless bandeau is surprisingly secure and dig-free. It also doubles as the perfect, super-smooth tube top! 

With a modern long-line silhouette and a solid amount of support for busts of all sizes (see the product page video in the bottom right hand corner of this page to see what we mean!), this strapless bikini top is always a go-to. Like all onewith swim bikini tops, this top features removable cups. 

For the full swimwear that feels like underwear experience, why not complete the look with our Huntington Thong Bikini Bottom That Fits Like Underwear? These two were made for each other, *and* for you.

📏 fit note: looking for more size advice? Our size guide can be found here. Pro tip: we don’t size by cup! Order Harkness in whatever size you’d normally get in a tight cami or bralette. For this style, size DOWN if you're in-between sizes. Don't size up to accommodate for your cup.

    Best top ever

    I ordered a size medium. I’m a 38DDD, it’s a wee bit tight but needed considering their size. It’s so cute and honestly is one of the most well thought out suits I’ve ever owned. Well worth the money.

    Love it!!

    I was skeptical because bandeau tops have never been comfortable or stayed up. It took a little finagling to get on, but it’s not going anywhere. It’s super comfortable, supportive and flattering. I’m a 34D/32DD and bought a medium. Can’t wait for some prints to come out!!

    Hi Dawn, thank you so much for this review! Harkness is a style that has sneaky-support, and we're so glad to hear you found it to be super secure, flattering, and comfortable! While it may sound silly, finagling your Harkness to get it on is actually a sign that it'll be a perfect fit :) Enjoy your onewith 🌊
