Wash & Care

Recommended: Machine wash on a gentle cycle, or handwash using natural detergent inside a delicate wash bag.

Avoid: Bleach and fabric softeners. They break down natural fibers and shorten the life of your undies.

Drying: Tumble dry on low, or better yet, lay flat or hang to air dry for maximum longevity.

Storage: Keep your undies in a cool, dry place. In humid environments, a dry storage bin with a bit of baking soda helps keep things fresh.

Comfort Guarantee & Return Policy

On your first order, contact us within 21 days of delivery if the fit is not right. Eligible single underwear pieces qualify for an exchange or store credit. Sets, bundles and bralettes are excluded. Opened underwear cannot be returned; your first eligible pair is covered by Comfort First. Unopened items must remain in their original intact packaging. Read the full policy.

Way too big on me and had to pass on to someone else. But they’re very soft.

I love the color, feel, and fit. I just got them, so I'm not sure how they hold up over time.

I really like these underwear, I've been watching to slowing swap my underwear drawer from synthetic material to natural materials. After a lot of research, I decided to start with these and I'm very happy with that choice. Me neither regions are way less irritated. My only suggestion would be to make the waistband a bit wider. I feel like a wider waistband is less diggy and more comfortable

Very soft and comfortable! Feel so good knowing the fabric is not just safer than plastic/polyester but also good for my skin, and feels good.

The Cheeky Wins

I own every style Kiseau makes, and the cheeky wins. It sits broader across the hips and feels incredibly comfortable. I'm genuinely obsessed and have moved my whole rotation over to theirs. Pricey, but so worth it.

Mom Was Right

My mom recommended these and now I'm not going back. So comfy and well worth it, with great material and quality. The look and style are lovely, and the fit is great.

Sits Right Where I Want

I like my underwear to sit just on my belly button, and the cheekies hangs out right where I want it. I'm between a small and medium, so I bought both; I'm finding the small works best the more I wear it, while the mediums have become my lounge pairs.

A Revelation For Sensitive Skin

With sensitive skin and a lifelong struggle to stay comfortable and dry, these have been a revelation. No bunching, and they keep you dry.

I Adore My Cheekies

I adore my Kiseau cheekies. Both the fabric and the cut are really comfortable, and I love how breathable they are.

I had my doubts early on, mostly because it's such a new brand, but their customer service was great and their bikini style has slowly become my favorite pair in my underwear drawer.

Prefers The Larger Size

Lovely soft, comfortable fabric. I got a couple of mediums and several larges to compare, and while the medium is fine, I prefer the larger, since I dislike elastic that digs into me.

Lovely, But I Sized Up

The fabric feels lovely, and it's durable too. I ordered a size up from what fits me best, so I'll buy more in the right size.

Misses The Elastic-Free Version

I owned the bikini style already from collection 1, but not the biggest fan of the new elastic. I loved the old one because it was elastic-free. The fabric however is still unbelievably soft.

Right For My Stage Of Life

These have completely changed things for me. I'd struggled to find something comfortable, light, and right for my stage of life. Still in my old brand, I wanted something sturdier that didn't read as dated. These are high quality and feel so soft. Thrilled it's a Canadian owned brand. They're going places!

Why we're here

Designed to undo decades of compromise in women’s intimates.

We started Kiseau because we couldn’t accept how little the apparel industry seemed to think about the people actually wearing it.

Whether you're detoxing your life, navigating hormonal changes, UTIs, yeast infections or sensitive skin, we believe intimate wear deserves more care.

So we set out to create something more thoughtful from the beginning, from the fabrics we choose to the way each piece feels against your skin.

For too long, we’ve accepted fabrics, finishes and materials that never really felt like they were made with our bodies in mind. We wanted to question that, and make the pieces closest to you with more care, intention and consideration.

Kiseau is independently owned and designed with the kind of care we would want for ourselves and the people we love.

More than anything, we want Kiseau to feel human.

Sizes shown are a measurement guide. Available sizes vary by style.

A little measuring goes a long way.

Use a soft measuring tape and keep it level. Measure your body, rather than a garment.

Waist

Gently bend to one side to find your natural waist. Wrap the tape around that point, level and comfortably snug.

Hip

Wrap the tape around the fullest part of your hips and bum. Keep it snug but not tight, sitting evenly around your body.

Bust

Wrap the tape around the fullest part of your bust, parallel to the floor and comfortably snug. Keep it straight across your back.

Band · relaxed to snug

Wrap the tape directly under your bust, around your rib cage. Keep it level and snug, exhaling gently as you measure.
