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.
