Finally. A swimsuit that fits like it was made for you.

You know the feeling.

Standing in the dressing room, pulling at the straps, trying every angle in the mirror.

This one is different.

The sheer mesh waist skims your middle without flattening it. The ruched skirt drapes over your hips like it was meant to be there.

You twirl. You smile. You don't change out of it.

Ready to wear out of the package. No padding to fix. No straps that dig.

A summer favorite reordered again and again.

Mesh waist that skims, never exposes
The sheer mesh panel sits flat against your body to slim the middle while keeping the look soft and feminine. No squeezing. No bulge. Just a smoother line from chest to hip.

Built-in skirt for instant coverage
The ruched drawstring skirt drapes over hips and thighs so you skip the cover-up. Pull the side tie tighter for more shape, looser for more flow. Your choice, every time.

Supportive V-neck for a full bust
The gold U-ring V-neckline lifts and centers without a wire. Removable padding adds shape if you want it, comes out if you don't. D-cups stay put.

Quick-dry fabric that keeps its shape
Polyester-spandex blend dries in minutes and snaps back after every wear. No sagging skirt. No baggy seat. Looks the same on day 30 as day 1.

Flatters front, side, and back
Designed for real curves: full bust, defined waist, wider hips. Every angle is the good angle — even the one you usually avoid in photos.

Frequently asked questions

Is the mesh see-through?
The mesh panel is sheer over the waist but designed to slim and smooth, not expose. It sits flush against your body and reads as a soft visual cutout, not skin.

Will the skirt ride up in water?
The skirt has weighted draping and the drawstring keeps it anchored. It drapes naturally whether you're walking, sitting, or swimming.

Can I take the padding out?
Yes. The cups have removable padding inserts. Pull them out for a softer look or leave them in for more lift.

Does it run small?
This style runs about one size smaller than US sizing. We recommend sizing up — check the size chart for exact measurements.

Specifications

  • Size: S, M, L, XL, 2XL (see size chart)

How to wash

  • Hand wash cold with mild detergent
  • Do not bleach
  • Lay flat or hang dry
  • Do not tumble dry — heat damages the spandex and mesh

Do these run true to size? They fit true to size for most. If you're between sizes or prefer a more relaxed fit, we suggest sizing up one.

Can I wear this to the office? Yes. Styled with the right pieces, it reads polished and professional while keeping the silhouette clean.

Will the fabric fade after washing? The fabric is pre-washed to soften the feel and minimize fading. Wash cold and hang dry to keep the color rich.

Wrong size? Displeased? No problem! If for any reason you are not satisfied with the product, we offer a 60 day return policy.

To minimize our carbon footprint, we don't keep all our products in stock. Instead, we make them on demand, which may result in slightly longer delivery times. This approach lets us offer better prices, benefits the environment, and helps avoid unnecessary waste. Once your payment is confirmed, we'll begin processing your order right away — it typically takes 1–3 business days to prepare and ship. After dispatch, you'll receive a confirmation email with a tracking number, and you can follow your order anytime on the Track Your Order page. On average, you'll receive your order within 3–8 working days after dispatch.
