The OverKini Explained: Why Layered Swimwear Is a Game-Changer

It seems counterintuitive, but swimwear has rarely been designed with real women, or real bodies, in mind. If you've ever struggled to find a suit that fits your bust but flatters your waist, or gives you support without sacrificing style, you’re not alone. 

We’ve been there—frustrated by years of swimwear that didn’t fit, flatter, or support. That’s exactly why we created the OverKini, a first-of-its-kind layered swim system designed to provide lift and coverage without compromising on confidence or comfort.

So, What Is an OverKini?
The OverKini is our signature innovation: a sleek one-piece swimsuit made to be layered over our Balconette bikini top, expertly designed by bra specialists and available in a full range of bra sizes. Think of it as the best of both worlds—the lift and structure of a bikini with the streamlined, confident feel of a one-piece.

Where most one-pieces fall flat (literally) in the bust or lose shape in the water, the OverKini is designed to work with your body, not against it.

The Details: What Makes It Different

Each OverKini style features:

  • A lightweight top layer that drapes effortlessly over your bikini top, smoothing without clinging

  • A shaping power mesh bottom half that offers 360 degrees of sculpting coverage

  • No-dig leg openings for a smooth, comfortable fit that stays put

  • Intentional layering that enhances your natural shape—without squeezing or restricting

And because it’s designed to pair with our Balconette Top, you get all the underwire support and secure lift where it matters most.

Who It’s Made For

We designed the OverKini for those who want real support—without sacrificing style. If you’ve ever layered a sports bra under a swimsuit (guilty), doubled up on suits for extra coverage, or left the beach early because your suit just wouldn’t stay in place, this system was built for you.

It’s also perfect for women with longer torsos, large cup and small band sizes, or anyone who wants the option to mix and match sizing, colors, and support levels between top and bottom.

Why It Works

The beauty of the OverKini is that it adapts. You can choose the amount of coverage you want, the level of support you need, and the style that suits your body and your mood. Want more cleavage? Less? More compression or a more relaxed fit? Build your perfect suit by pairing the Balconette Top with the OverKini style that works for you.

And because we believe in swimwear that lives up to real life, every OverKini is crafted from sustainable Italian fabric, with UPF 50+ protection and thoughtful design details that keep you feeling confident, supported, and free to move about your day.
