The tankini that drapes, not clings

You know that feeling at the beach — tugging your top down, keeping your towel close, hoping no one's looking.

This set changes that.

The flowy blouson top skims your midsection instead of clinging to it, and the matching boardshorts stay put whether you're walking the shore or wading in.

You get coverage that actually covers. And a set that finally feels like you again.

One of our most reordered swim sets this season

Skims the tummy, never clings
The flowy blouson top drapes gently away from your midsection, even when wet — so you get real coverage, not fabric stuck to your skin.

Boardshorts that actually stay down
The drawstring waistband and longer 4-inch inseam keep the shorts in place while you walk, swim, or chase the kids. No riding up.

Matching set, zero guesswork
Top and shorts are made to go together — same print, same fit, same fabric. No mixing, no matching, no wondering if it works.

Quick-dry polyester stretch
Dries fast after a swim so you're not sitting in cold, wet fabric. Keeps its shape wash after wash.

Frequently asked questions

Does the top stay flowy when it's wet?
Yes. The blouson drape is cut wide enough that it keeps its shape in the water and skims the midsection instead of sticking to it.

Is the top lined?
Yes. The top has a soft inner lining so it stays opaque, even when wet.

Can I wear the shorts on their own?
Absolutely. Many customers wear the boardshorts as beach cover-ups or over their favorite bikini bottoms.

How do I know which size to pick?
Check the size chart. If you're between sizes, size up — the fit is meant to skim, not squeeze.
