Matching Sibling Outfits & Pajamas

Organic cotton matching sibling sets that let a big sister or big brother and a new baby dress alike. Our two-piece pajama sets and coordinating outfits come in the same playful prints across sizes newborn through 6 years — so siblings can match from day one. Designed in New York since 2003, soft against baby's skin, with no harmful chemical dyes.

Matching sibling pajamas

Our matching sibling pajamas are two-piece organic cotton sets — a long-sleeve top and bottoms — in coordinating prints sized from baby through toddler (up to 6 years). Pop the baby in one size and the big sibling in another, same print, instant matching photo. Soft, breathable, and made to be handed down.

Big sister & big brother sets

Looking for big sister little sister outfits or big brother little brother matching sets? These coordinated organic cotton pieces make the "I'm a big sister/brother" moment feel special, and photograph beautifully. A favorite for announcements, hospital meet-the-baby photos, and holiday cards.

A gift from the new baby

One of the most-loved new sibling gifts: a matching set given "from the new baby" to the big sister or big brother, so the older child has something special of their own when the baby arrives. Our NYC Print Sibling Pajama Gift Set pairs matching pajamas with a hand-knit NYC taxi toy — a ready-to-give gift for siblings of a new baby. Ships within 1–2 business days; gift boxing available.

Why Estella sibling sets are different

Every matching set is made from organic cotton, with no harmful chemical dyes and cotton grown without synthetic pesticides — soft against baby's skin and built to last through hand-me-downs. Designed in New York by a small family brand since 2003. Never mass-produced, never on Amazon.
