The tankini you can finally relax in.

You know that moment by the pool.

You tug. You smooth. You wrap a towel back around.

This tankini set has drawstring sides that gather softly around your middle, so the tank stays put and your tummy stays covered — even when you sit, swim, or chase the kids.

The boy-shorts cover what bikini bottoms don't.

The crisscross V-neck looks modern, not matronly.

Slip it on, walk down to the water, and stay there.

A returning summer favorite, year after year.

Stop tugging at your swimsuit all day
The adjustable side drawstrings gather the fabric softly around your tummy, so the top stays put when you sit, bend, or swim. No more constant adjusting.

Boy-shorts that stay where they belong
Full-coverage boy-shorts give you more skin coverage than bikini bottoms — no riding up between the thighs during swimming, walking, or beach volleyball.

A V-neck that looks modern, not matronly
The crisscross strap detail at the V-neck draws the eye up, frames the décolletage, and gives this tankini a fashion-forward edge most modest swimwear misses.

Moves with you, dries in minutes
The polyester-spandex blend stretches with every movement and dries quickly so you're not sitting in a heavy, wet suit all afternoon.

Frequently asked questions

Are the side drawstrings actually functional?
Yes. Pull them tighter for more ruching and tummy coverage, or loosen them for a relaxed drape. They tie at the side hip.

Is the fabric see-through when wet?
No. The polyester-spandex blend is fully lined and stays opaque in the water.

Do the boy-shorts have a built-in liner?
Yes, the boy-shorts are lined for comfort and discretion.

Can I wear the tank top separately as a regular top?
Most customers wear it strictly as swimwear since the cut and fabric are designed for the water, but it works as a beach cover-up over bikini bottoms too.
