Finally, A Tankini That Stays Where You Put It
You shouldn't have to tug at your swimsuit all day.
The Coastellaโข longline tankini set is built for real movement โ the tank stays down, the boyshorts stay put, and the crisscross V hugs you right where it should.
Walk the shore. Chase the kids. Sit on the towel. Stop checking the mirror.
This is the suit you'll reach for all summer.
One of our most reordered beach sets this season
โ Longline tank covers the midsection
The tank runs past your hips so you can move, sit, and swim without tugging it back down. No riding up. No gap at the waist.
โ Crisscross V lifts and holds a full bust
The crossed front strap gives real support up top โ even D-cups stay in place through every wave and walk.
โ Matching boyshorts, full coverage
More skin covered than a bikini bottom, no dig at the waist. Side ties let you adjust the fit through the day.
โ Quick-dry 4-way stretch fabric
The polyester-spandex blend moves with you and dries in minutes โ so you're not sitting in a wet suit on the ride home.
โย Sizes SโXL, built for real curves
Designed with curvier women in mind. The longline cut and ruched sides flatter the waist, hips, and stomach โ not just the model.

Does the tank stay down when you swim?
Yes โ the longline cut and stretchy fabric are designed to stay in place during swimming, walking, and bending. It doesn't ride up like a regular tankini.
Is the fabric see-through when wet?
No. The polyester-spandex blend is thick enough to stay fully opaque wet or dry, including in lighter prints.
Do the boyshorts dig in at the waist?
The waistband is soft and stretchy, not elastic-tight. Most curvier women size up one for the most comfortable fit on the hips.
Can I wear this for water aerobics or beach volleyball?
Yes โ the 4-way stretch and full coverage make it ideal for active beach and pool use, not just lounging.
