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.

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.
