📏 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
XS58–62 cmPetite frames
S63–67 cmSlim build — most common
M68–73 cmAverage build
L74–79 cmCurvier figures
XL80–85 cmPlus size
XXL86–92 cmExtended plus

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 tankini

Knot-front charm.
Tankini convenience.

Four reasons the Sabine is the dressier of our two ostomy tankinis.

Signature fabric-knot detail

Gathered fabric at the centre-front of the bodice creates a flattering focal point at the chest AND draws the eye away from the waist — masking any pouch outline through the wet bottom.

Two-piece bathroom convenience

Lift just the top to drain or change the pouch in a public restroom — no full undress required. Faster, more discreet, more dignified than a one-piece.

Inner pouch pocket

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

Anti-leak, anti-pancaking, fast-dry

The high-waisted, reinforced waistband locks the pouch in place. Engineered swim fabric dries in minutes, survives chlorine and salt, all summer long.

How it works

Three steps. Knot-front confidence.

Slip on the bottom. Tuck the pouch. Pull on the knot-front top. Walk in.

Step 1

Slip on the bottom

Step into the high-waisted bikini bottom and pull it up above your stoma. The waistband sits firm and supportive.

Step 2

Tuck the pouch

Place your ostomy pouch inside the inner pocket. The pocket holds it flat against the body — invisible under wet fabric.

Step 3

Pull on the knot-front top

Slip the tankini top over your head — the gathered fabric-knot at the centre-front draws the eye to the chest. Walk poolside with total confidence.

More than swimwear

The dressed-up tankini
made for ostomates.

Engineered for ileostomy, colostomy and urostomy. The Sabine's signature knot-front detail flatters the silhouette while the two-piece structure keeps bathroom breaks dignified.

Flatter the chest. Hide the rest.

The signature fabric-knot at the centre-front of the bodice creates a flattering visual focal point at the chest — drawing the eye away from the waistline and masking any pouch outline through the wet bottom.

Inner pocket

Pouch invisible. Stays flat.

The stoma-level inner pocket on the bottom holds your pouch flat against the body — no shifting mid-swim, no visible outline through wet fabric.

Anti-leak high-waisted Sabine bottom
Proven protection

Anti-leak. Anti-pancaking.

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

Bathroom-ready

Lift the top. Drain. Done.

Two-piece convenience means you don't have to fully undress at a public pool restroom to manage the pouch — just lift the tankini top, access the inner pocket, drain and re-tuck. Faster, more discreet, more dignified than a one-piece.

The knot is so flattering

"I was sceptical the knot would do anything but it really lifts the look. The gathered fabric draws the eye up to the chest and the waistline disappears. I felt dressed-up, not 'medical swimwear'. Wore it to a beach club and got compliments."

Sarah M. · USA · 3 months ago Amazon
★★★★★

Two-piece convenience finally

"Coming from one-piece ostomy swimsuits, the lift-only top is a game changer. Drain the pouch in 30 seconds without taking off the whole suit. Plus the knot front looks like a proper holiday tankini, not a hospital one."

Anna K. · UK · 6 weeks ago SIIL Store
★★★★★

No leaks, no pancaking, full swims

"Swam laps for an hour, snorkelled, walked the beach. The pouch stayed flat the whole time and drained normally afterwards. The high waist holds everything in place."

Linda P. · Spain · 2 months ago SIIL Store
★★★★★

Dressier than the Chloe

"I have both Sabine and Chloe. Chloe for family beach days when I want max coverage; Sabine for resort dinners and beach clubs when I want to feel a bit more dressed up. The knot makes it feel like a real swim look."

FAQ

Everything you want to know

What does the fabric-knot detail actually do?
The knot is a permanent design feature gathered at the centre-front of the bodice. It creates a flattering visual focal point at the chest while drawing the eye away from the waist — masking any pouch outline through the wet bottom. The bodice is fully lined for opacity and the knot stays in place during swims.
How does Sabine differ from the Chloe tankini?
Both are SIIL two-piece tankinis at $89.99. Sabine has a knot-front detail at the bodice (draped, feminine, focal-point styling) — choose if you want a dressed-up swim look. Chloe has a plain long-line top (modest, full-torso coverage) — choose if you want maximum modesty for post-op recovery or family beach days.
Is the Sabine a complete set, or just one piece?
It's a complete two-piece tankini set — knot-front tankini top PLUS the high-waisted bottom with the inner pouch pocket. Both pieces ship together, sized identically. No need to buy a top separately.
Can I lift just the top to access my ostomy pouch?
Yes — that's the main practical advantage of a tankini over a one-piece. The two-piece construction means you can lift the top alone (no need to fully undress) to drain or change the pouch in a public restroom. Faster, more discreet, more dignified.
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 — both pieces are sized identically. Between sizes? Choose the larger — the high waistband and bodice adapt comfortably. We accept exchanges within 30 days if the size isn't right.
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.
