Ostomy Panties Classic
The Ostomy Panties Classic are SIIL's most popular mid-rise intimate panties — designed for ostomates who want everyday-style underwear that quietly hides the pouch, fits like the panties they wore before surgery, and works under every wardrobe staple. Cut from a soft, breathable, antibacterial knit, the Classic features a hidden inner pocket that holds the ostomy bag flat against the abdomen, a comfortable mid-rise band that sits at your natural waist, and two timeless colours (beige and black) that pair with light or dark clothing.
Mid-rise ostomy panties
The Classic cut sits at your natural waist — neither high above nor below the stoma — for the most-loved everyday panty silhouette. This makes the Classic the perfect daily-wear pair for ostomates who don't want a high-waist look, who prefer a discreet hidden pouch under regular clothing, and who change pouches several times a day (the mid-rise opening makes pouch access easier than a high-waist).
Ostomy panties for women
Sofía and Classic are SIIL's two flagship feminine ostomy panties. Sofía is high-waist (above the stoma, more hernia support); Classic is mid-rise (at the natural waist, easier pouch access, more "normal" panty feel). Both have the same hidden inner pocket, antibacterial knit, beige + black colourways, and 6 sizes. Choose Classic if you want the most familiar everyday panty fit.
Beige & black ostomy panties
Beige is engineered to disappear under nude, white and pastel clothing — exactly the wardrobe staples (white t-shirts, beige slacks, summer dresses) where black underwear would show through. Black melts under jeans, dark trousers, dresses and structured suits. Switch between the two colours using the swatch above — same fit, same fabric, same inner pocket.
Ileostomy panties & colostomy briefs
The hidden inner pocket fits one-piece and two-piece pouches from Coloplast, Hollister, ConvaTec, B. Braun, Pelican, NuHope, Marlen and Welland — across ileostomy, colostomy and urostomy use cases. The stretch knit adapts to pouch volume changes throughout the day, so the morning empty-bag fit feels just as comfortable as the evening full-bag fit.
Discreet ostomy underwear for daily wear
The Classic is engineered for the everyday: school runs, office work, gym sessions, weekend errands, dinner with friends. Soft on the skin, machine-washable, antibacterial — built to last 12+ months of daily use. Pair with our SIIL Ostomy Wrap or MIA Wrap when you need additional compression for sport.
Ostomy Panties Classic FAQ
What's the difference between Classic and Sofía panties?
Sofía has a high-waist band that rises above the stoma (more pouch coverage + hernia support). Classic has a mid-rise band that sits at the natural waist (more familiar everyday panty feel + easier pouch access). Both have the same hidden inner pocket, soft antibacterial knit, beige + black colourways and 6 sizes.
What size of Classic panties should I order?
Use the size guide above the Add-to-cart button. Measure your natural waist (the narrowest part above your belly button) and your hip at the widest point. Between sizes? Choose the larger — the soft knit adapts down 4 cm comfortably. We accept exchanges within 30 days if the size isn't right.
Will Classic fit my ostomy pouch?
Yes — the inner pocket is sized to fit one-piece and two-piece pouches from Coloplast, Hollister, ConvaTec, B. Braun, Pelican, NuHope, Marlen and Welland. The pocket fabric is stretch elastic so it adapts to different pouch shapes and capacities.
Can I wear Classic to sleep?
Yes — Classic is soft and breathable enough for overnight wear. Many customers prefer sleeping in Classic for all-night pouch security; the mid-rise band keeps the pouch in place without restricting movement.
How do I wash Classic?
Machine-wash at 30 °C on a gentle cycle, inside out, with similar colours. Air-dry flat. Avoid bleach, fabric softener and the tumble-dryer to preserve the elastic and antibacterial finish. With normal care, one pair lasts 12+ months of daily use.

Feels like my pre-surgery panties
"After my colostomy I assumed I'd never wear everyday underwear again. Classic feels exactly like the mid-rise panties I wore before. The pouch tucks into the pocket and disappears. Game-changer."
Pouch access is so easy
"I tried high-waist ostomy panties first but pouch changes were a hassle. Classic's mid-rise sits right at my waist and I can drain/change without pulling everything down. Bought 5 pairs."
Beige is the perfect nude
"I wear a lot of white in summer and the beige Classic disappears under everything. So happy I stopped buying high-street panties that bunched around my pouch."
No leaks under fitted dresses
"Wore Classic under a slim dress to my niece's christening. The pouch was completely hidden — no one could tell. The fabric is so soft I forgot I had it on by midday."
Fits my Coloplast pouch perfectly
"Worried the pocket would be too small for my SenSura Mio drainable bag. Fits beautifully — stretchy, supportive, holds the pouch flat. Ordered four pairs in beige and black."
Wash after wash, still soft
"Twelve months of daily wear, machine-washed at 30 °C — the elastic is still firm, the colour hasn't faded. Best ostomy underwear investment I've made."
Same waist. Different day.
