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.
Now lets find what style feels like you...
