📏 Size guide
Please pick a size before adding to cart.
Measure your waist (cm) at the level of your stoma. Top is sized to match the bottom:
SizeWaist (stoma level)Best for

S63–67 cmSlim build — most common
M68–73 cmAverage build
L74–79 cmCurvier figures
XL80–85 cmPlus size

Tip: measure with a soft tape at the level of your stoma, exhale gently. Between sizes? Choose the larger — the high waistband appreciates the extra coverage above the stoma. Both pieces are sized identically.

Why this bikini

High-waisted coverage.
High waist convenience.

Four reasons the Marbella high-waisted bikini outperforms every other ostomy swimsuit.

High-waisted bottom for pouch access

The high-rise bottom rises above the stoma and keeps the pouch flat and completely hidden — no waistband digging, no peeking. Full concealment with a flattering line.

Two-piece, easy access

As a two-piece, you simply lower the high-waisted bottom to drain or change — no zipper, no peeling off a wet one-piece in a public cubicle. Bathroom convenience without sacrificing coverage.

Inner pouch pocket

Stoma-level inner pocket holds your ostomy pouch flat against the body — no shifting, no sloshing, no visible outline through wet fabric.

Anti-leak, anti-pancaking, fast-dry

Light compression keeps the pouch flat. Engineered swim fabric dries in minutes and survives chlorine and salt — built for real ocean and pool days.

How it works

Three steps. Total confidence.

Step in. Tuck the pouch. Pull it up. Walk in.

Step 1

Step in & pull up

Step into the high-waisted bottom and pull it up over your stoma, then slip on the flutter-sleeve top. The high rise sits above the pouch, the soft straps frame the shoulders.

Step 2

Tuck the pouch via the high waist

Position your ostomy pouch behind the high-rise waistband. The high waist holds it flat against the body — fully hidden and invisible under wet fabric.

Step 3

Walk in

Step poolside with total confidence. When you need to drain the pouch later, just lower the high-waisted bottom — no need to undress completely.

More than a swimsuit

The accessibility breakthrough
ostomates have been waiting for.

Engineered for ileostomy, colostomy and urostomy. The Marbella breaks the historical tradeoff between full coverage and easy access — high-waisted concealment with two-piece convenience.

Drain without undressing.

Because the Marbella is a two-piece, you simply lower the high-waisted bottom to drain or change the pouch — no zipper, no taking off a whole one-piece. The freedom ostomates have been asking from a swimsuit for years.

Modest, modern, photogenic.

The flutter-sleeve top adds a soft, feminine line while keeping you free to move. Resort-ready aesthetic that pairs effortlessly with a sarong, kaftan or swim shorts.

Proven protection

Anti-leak. Anti-pancaking.

Light compression and the reinforced inner pocket keep the pouch flat — customers report swimming, snorkelling and paddle-boarding without a single leak.

Resort-ready

Photographs beautifully. Holds up beautifully.

The Marbella is the bikini you reach for first when packing for a trip. Flattering high-rise silhouette photographs at any time of day. Engineered fabric survives multiple seasons of pool, salt and sun.

The high waist finally solved my pool dread

"Every previous swimsuit meant peeling off a wet one-piece in a public restroom to drain my pouch. With Marbella I lower the high-waisted bottom, drain, pull it back up, walk out. 30 seconds, dry above the chest, total dignity."

Full coverage that actually photographs well

"Flutter sleeve, flutter-sleeve, clean lines — I wore it at a Greek resort and got compliments. Most full-coverage swimsuits look matronly; this one looks like a proper holiday swimsuit. Hides everything I need hidden."

No leaks, no pancaking, full swims

"Swam laps for an hour, snorkelled at the reef, walked the beach. The pouch stayed flat the whole time, the fabric compression keeps everything in place, and the high waist held perfectly under salt water."

Best ostomy bikini I've owned

"I have ileostomy and used to dread vacations. The two-piece access is genius — drainage takes a fraction of the time, and the fabric stays dry around the chest where I lower the high-waisted bottom. Already on my second season."

FAQ

Everything you want to know

How does the high-waisted bikini hide the ostomy pouch?
The high-waisted bottom sits above the stoma and conceals the pouch completely. To drain or change, you simply lower the bottom — no zipper, no taking off the top, no peeling out of a one-piece. This two-piece freedom is the main reason customers choose Marbella over a traditional high-waisted bikini.
Is the Marbella a one-piece or a two-piece?
It's a two-piece: a flutter-sleeve bikini top plus a high-waisted bottom that rises above the stoma to conceal the pouch. The two-piece design gives you easy bathroom access — lower the bottom to drain — while the high rise keeps full coverage.
How do I pick the right size?
Measure your waist (in cm) at the level of your stoma. Use the size guide above the Add to cart button. Between sizes? Choose the larger — the engineered fabric provides light compression and adapts comfortably. We accept exchanges within 30 days if the size isn't right.
Will it fit my ostomy pouch brand?
Yes. The inner pocket fits drainable, mini and two-piece pouches from Coloplast, Hollister, ConvaTec, B. Braun, Pelican, Welland and most independent brands. The stretch fabric adapts to pouch shape and volume during a swim.
Is the fabric safe in salt water and chlorine?
Yes — the fabric is engineered for both pool chlorine and ocean salt. Rinse with fresh water after every swim and air-dry flat in the shade for multiple seasons of wear.
What if it doesn't work for me?
30-day no-questions-asked returns. If the size or fit isn't right, email hola@siilostomy.com and we'll refund or exchange.
