Product description

Finally, A Tankini That Stays Where You Put It

You shouldn't have to tug at your swimsuit all day.

The Coastella™ longline tankini set is built for real movement — 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

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.

Crisscross V lifts and holds a full bust
The crossed front strap gives real support up top — even D-cups stay in place through every wave and walk.

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.

Quick-dry 4-way stretch fabric
The polyester-spandex blend moves with you and dries in minutes — so you're not sitting in a wet suit on the ride home.

✓ Sizes S–XL, built for real curves
Designed with curvier women in mind. The longline cut and ruched sides flatter the waist, hips, and stomach — not just the model.

Frequently asked questions

Does the tank stay down when you swim?
Yes — 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 — the 4-way stretch and full coverage make it ideal for active beach and pool use, not just lounging.

Really pleased with this top. The fit is comfortable and the neckline is very flattering. It looks put together without feeling too dressy, which is exactly what I wanted.

This was my first order from Studio Gisèle and I’ll definitely be ordering again. The dress is light, comfortable and fits beautifully. Delivery was smooth and kept me updated.

This cardigan is so soft and comfortable to wear. The fit is relaxed without feeling too loose, and the cream colour is really flattering. It’s one of those pieces that works with almost everything.

Where women with good taste find what they love

We're Studio Gisèle, where women with good taste find what they love

After years of carrying this alone, I'm finally passing it on to my daughter, Aubrey. It's harder than I imagined.

Fabric found in far-off markets. Colours borrowed from cultures I fell in love with along the way. A label built from nothing but my hands, my journeys, and a single sewing machine. All stitched to feel like more than just clothing.

That's the heart of what I built, and Australia is still woven through every seam.

Letting go means saying goodbye to something I raised like a child, piece by piece, year by year. But I'm certain of one thing. Aubrey is ready, with her own eye, her own spirit, and a vision that will carry this story further than I ever could.

Thank you for being part of this story. It was never really mine alone.

With all my love,
Gisèle x
