PRODUCT DETAILS

DESIGNED FOR EVERYDAY WEAR

The swimsuit you'll actually want to wear

You know that moment before the pool.

The mirror. The pulling. The sigh.

This set changes that. The flowy empire tankini floats over your midsection — no cling, no tug — and the matching boy shorts cover your hips and thighs so you can sit, walk, and swim without adjusting.

The bright print on the straps and side panels pulls the eye up, lengthening your whole silhouette.

Slip it on and it's ready to wear. No fussing. No cover-up needed.

A curvy favorite, season after season

Floats over your tummy, doesn't cling
The empire A-line drape sits under the bust and skims over your midsection instead of hugging it. You get coverage that moves with you — poolside, in the water, sitting down.

Boy shorts that stay down, not up
Mid-thigh shorts with a wide waistband cover your hips and thighs and stay in place. No rolling, no riding up when you walk or sit.

Wide straps and V-neck lift for full busts
Soft gathers at the neckline and wide, secure straps give real support for a D-cup and up. Move, bend, swim — everything stays where it should.

Print placement that lengthens your silhouette
Vertical print accents on the straps and side panels draw the eye up and down, not across. The classic black base is slimming — the color is where you want it.

✓ Resort-ready, not matronly
Flattering coverage doesn't have to mean frumpy. This set was designed to look styled at the beach, the pool, or the resort — not like a swim dress from another decade.

Frequently asked questions

Does the top stay down in the water?
Yes. The empire drape is weighted by the seam under the bust and moves with you rather than floating up. Most women wear it swimming, wading, and sitting poolside without issue.

How does the sizing run?
This set is designed with generous plus-size cuts (US 14 to US 24). Check the size chart against your bust, waist, and hip measurements. If you're between sizes, size up for the most comfortable drape.

Do the boy shorts roll up when you walk?
The wide waistband and mid-thigh cut are designed to stay in place during normal movement — walking, sitting, swimming. They fit like a bike short.

Can I wear the top separately with regular shorts?
Yes. The tankini top is styled enough to pair with denim shorts or a skirt as a beach top, though it's cut for swim use.
