The one-piece that gets noticed before she does

Some swimsuits cover you up.

This one shows up with you.

The deep plunge. The wrap-waist that ties you in. The high-cut legs that stretch your silhouette to forever. The adjustable gold-hardware straps keep everything exactly where you put it — so you stop tugging and start owning the moment.

Slip it on. Walk slow. Let them look.

A summer favorite for women who book the trip for the suit

The plunge that holds its ground
Adjustable gold-hardware straps mean no slipping, no tugging — the V-neckline stays exactly where you set it, even when you move.

Wrap-waist that sculpts your hourglass
The crossover band cinches your middle and frames your hips, giving you that snatched silhouette without shapewear underneath.

High-cut legs that add inches
The daring leg line elongates your frame and lifts your shape — instant statuesque, even barefoot at the pool.

78% nylon, 22% spandex — moves with you
Premium 4-way stretch hugs every curve without digging in, and bounces back wash after wash — no sag by day three.

The back view that finishes the look
Crisscross straps with gold buckles plus ruched booty detail mean every angle is the front — walk away and they'll still be watching.

Frequently asked questions

Is the fabric see-through when wet?
No. The 78% nylon, 22% spandex blend is fully lined and keeps its opacity in and out of the water.

Will the deep plunge stay in place?
Yes. The adjustable shoulder straps with gold-hardware buckles let you customize the fit to your bust, so the V-neck stays exactly where you set it.

Does it work for fuller busts?
The adjustable straps and wrap-waist give support up through D-cup. For larger cup sizes, we recommend sizing up one for extra coverage.

How does the sizing run?
Standard US sizing. If you're between sizes or have a fuller bust or hips, size up — see the size chart for measurements.

Size Bust Waist Hip

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.
