A calm sky blue flannel gives shape to the Women’s Blue Unicorn Onesie

For anyone who finds pink a little loud, the blue unicorn onesie for adults keeps the magic and cools the palette. The body is a clear sky blue, softened by a white belly panel and finished with bright pink cuffs that echo the ears. It is the version of the legend made for a quiet evening at home.

A golden horn rises above the face, framed by two pink lined ears, while a small pink tail trails behind. The front closes with buttons, the wrists and ankles are elasticated, and the flannel keeps its loft wash after wash, so the onesie looks the same on the tenth night as on the first.

Men’s Blue Unicorn Onesie for cold nights and long films

This adult blue unicorn onesie was cut for comfort rather than show. The shoulders move freely, the waist never pinches and the fabric is warm enough to make a blanket pointless. It suits a weekend in a cottage as well as a Sunday that never really starts.

Blue also stands out in a group shot where everyone else went pink. Order it for a pyjama party, a winter break with friends or simply to improve the hours between dinner and sleep. One piece, no styling required.

Meet the rest of the blue herd

The kids blue unicorn onesie dresses a child in the same sky blue for a matching duo. For a deeper shade, the purple unicorn onesie trades the blue body for a rich violet. More colours and prints are waiting in the unicorn onesies collection.

Frequently Asked Questions

They’re made to keep you warm on the sofa through autumn and winter, so yes, they’re cosy. The relaxed fit lets air move around, though, so you won’t get that stuffy feeling you get from tight pyjamas.
Machine wash at 30°C on a gentle cycle. Turn them inside out and pop them in a mesh laundry bag to protect the hood. Skip the tumble dryer and the iron. They air-dry quickly and fluff right back up on their own.
Yes, every onesie we sell is unisex. The roomy cut works for men and women alike, our kids’ styles fit girls and boys just the same, and our baby sizes are cut the same way for everyone. Just check the size chart to find your fit.
