📏 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 swim dress

A swimsuit
that looks like a dress.

Four reasons the Baby Doll is the most flattering ostomy swim piece in our collection.

Flared skirt overlay

The mid-thigh skirt floats softly over the high-waisted bottom underneath. Adds feminine A-line shape, extra hip coverage, and reads as a beach dress from the outside — not a swimsuit.

Hides hip & lower-abdomen lines

The skirt hangs below the bodice and naturally disguises any pouch outline through wet swim fabric. Extra modesty for ostomates who want their swim look to feel less revealing.

Inner pouch pocket

Stoma-level inner pocket on the bottom (under the skirt) holds your ostomy pouch flat against the body — no shifting, no sloshing, no visible outline.

Anti-leak, anti-pancaking, fast-dry

Light compression keeps the pouch flat. Engineered swim fabric dries in minutes, survives chlorine and salt. The skirt holds its flare wash after wash.

How it works

Three steps. Beach-dress confidence.

Step in. Tuck the pouch. Let the skirt fall. Walk in.

Step 1

Step into the dress

Step in and pull the swim dress up over your hips and chest. The high-waisted bottom underneath hugs the waist; the bodice frames the upper body.

Step 2

Tuck the pouch

Lift the skirt, peel down the high-waisted bottom, place your ostomy pouch inside the inner pocket. Pull the bottom back up and let the skirt fall back into place.

Step 3

Walk in

The skirt floats softly at mid-thigh — feminine, modest, beach-dress aesthetic. Walk to the pool, swim, sunbathe, lunch. Goes anywhere a beach dress goes.

More than swimwear

The dressiest swim look
in our collection.

Engineered for ileostomy, colostomy and urostomy. The Baby Doll is the swim piece that transitions from pool to lunch without changing — feminine, flattering, and built for confidence in the water.

A swimsuit. But it reads as a dress.

The mid-thigh skirt overlay floats softly over the high-waisted bottom underneath. Adds feminine A-line shape, photographs like a beach dress, and disguises any pouch outline through wet swim fabric.

Frames the upper body.

The bodice fits like a normal swimsuit top — supportive, flattering, with comfortable straps. Below the bust the skirt flares out for the dress effect.

Anti-leak inner pocket on the Baby Doll swim dress
Proven protection

Anti-leak. Anti-pancaking.

The high-waisted bottom and reinforced inner pocket keep the pouch flat — customers report swimming, snorkelling and walking the beach without a single leak.

Pool-to-lunch

One look. Multiple settings.

The Baby Doll uniquely transitions from pool to poolside lunch without changing. Pair with sandals and a chunky belt to wear it as a beach dress, or just walk straight from the water to the table — it all looks intentional.

Walked from pool to lunch without changing

"At a resort in Mallorca I walked straight from the pool to the lunch terrace and nobody blinked. The skirt makes it read as a beach dress — totally appropriate at the table, totally functional in the water. Multipurpose magic."

The skirt hides everything

"I have a colostomy and the inner pocket holds the pouch perfectly, but it's the skirt that gives me the confidence — even if there were any visible outline, the flared fabric below covers it completely. Best ostomy swimsuit purchase ever."

Anna K. · UK · 6 weeks ago SIIL Store

Photographs beautifully

"Every holiday photo I have in this swim dress looks like I'm wearing an actual dress. No 'swimsuit-on-the-beach' awkwardness. Looks intentional, dressed-up, feminine. Worth every penny."

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

Skirt didn't drag in the water

"Was worried the skirt would feel heavy when wet — it doesn't. The swim fabric dries fast and the skirt floats freely. Swam laps in it without any issue. Dries quickly after the swim too. Properly engineered."

FAQ

Everything you want to know

What is a swim dress, and how is it different from a regular swimsuit?
A swim dress is a one-piece swimsuit with a built-in skirt overlay made from the same swim fabric. The bodice fits like a normal swimsuit; the skirt flares from the waist down to mid-thigh, providing extra coverage over the lower abdomen, hips and upper thighs. From the outside, it reads as a "beach dress" rather than a swimsuit — the dressiest swim aesthetic available.
Does the skirt get in the way when swimming?
No — the skirt is made from the same fast-dry swim fabric as the bodice and floats freely in water without dragging. Customers swim laps, snorkel and paddle-board in it without issue. The skirt rises gently with movement and falls back into place when you stand.
How do I drain or change the ostomy pouch?
Lift the skirt up, peel down the high-waisted bottom underneath, access the pouch pocket — drain, change or re-tuck — and pull everything back up. The skirt provides natural privacy while you manage the pouch in a public restroom.
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.
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.
