The measurements shown are garment measurements. Each piece is designed with a relaxed fit to move and breathe with you through pregnancy, postpartum, and beyond. For general sizing information please see our size guide. If you need a little support finding your fit, don't hesitate to contact us, we're always happy to help.

Our sizing guide is a general guideline for helping you find the size that would fit you best. While our pieces are designed to flow with your changing body, each style has its own beautiful silhouette.

Our signature leakproof designs...

For feeding

Each signature piece features three discreet clips, cleverly concealed beneath the ruffle and designed for the real rhythm of motherhood. When it's time to feed, simply unclip the side and middle ones, then clip them back together when you're done. Easy enough to manage in the dark, half asleep, or out and about without a second thought.

For staying dry

Our removable, washable breast pads have a contoured shape designed to sit naturally around the bust. They provide discreet, reliable coverage that moves with you through feeding, sleeping, and everything in between. Each piece includes three breast pads - one to wear, one to wash, one spare, beautifully housed in a complementary bag.

Every Mirukī piece is created with one simple truth in mind: your body doesn't stay still during motherhood, and neither should your wardrobe.

That's why our silhouettes feature gentle elastic waistbands that support without squeezing, bust panels that accommodate changing cup sizes, and relaxed fits that flow beautifully whether you're 6 months pregnant or 6 months postpartum. We design for the magical, messy, ever-evolving journey of becoming and being a mother. Pieces that adapt as you do, supporting you through every leak, stretch, and sleepless night with the same quiet confidence.

Because when everything else feels new, your sleepwear should feel like home.
