Shopping for a one-piece swimsuit can feel like a gamble, especially if you have a longer or shorter torso. Traditional one-pieces are built on a one-torso-fits-all model, which means if you're not exactly in that average range, you're left with a suit that rides up, sags down, or flat-out doesn’t fit.

At Siren + Sage, we knew there had to be a better way. That’s why we created the OverKini: a game-changing swim layer designed to work with your body, not against it—no matter your proportions.

The Torso Struggle Is Real
If you’ve ever tried on a one-piece only to feel like you’re being stretched in two directions at the same time, you’re not alone. Most one-pieces are designed with a standard torso length, which can leave those with long torsos feeling constricted and those with short torsos swimming in excess fabric.

It’s not just uncomfortable—it also affects your confidence. A suit that pulls in the wrong places or gaps where it shouldn’t can throw off your whole vibe.

Enter the OverKini: A Layer That Adapts
The OverKini was designed with layering and adjustability in mind. Rather than relying on a single piece of fabric to define the fit, the OverKini layers over our Goddess Balconette Top—delivering sculpting coverage, shaping, and style without sacrificing comfort or flexibility.

Why it works for long torsos:

• The OverKini adds both physical and visual length without restricting movement or stretching too thin.

• It layers over the Goddess Balconette Top, providing full bust swimwear support without compromising coverage, even when stretched over a longer frame.

• Strategic seam placement works with your curves for a flattering, streamlined silhouette.

Why it works for short torsos:

• Since it's not a traditional one-piece, there’s no excess fabric bunching at the waist or chest.

• You get the look of a sleek, sculpted one-piece, with shaping and coverage that adjusts to your frame, not the other way around.
  

Style Meets Function

Beyond solving common fit frustrations, the OverKini is also:

• Made from luxe Italian UPF 50+ fabric for sun protection that moves with you.

• Designed to sculpt and smooth with hidden power mesh and intentional design lines.

• Versatile enough to wear layered over our bra-sized swimwear top, for extra coverage where you want it.

Love Your Layers

Feeling confident in your swimwear starts with embracing your body, not fighting against it. The OverKini is our solution to the forgotten fit issues that traditional suits often overlook. Because your proportions shouldn’t limit your options—they should help shape your style.

And because our base layer is a cup-sized swimwear top made specifically for D+ cup swimwear needs, you're getting support where it matters. Whether you need a little extra support or simply crave more coverage without compromising on style, this combo checks every box.
