Two star printed options land on the Women’s Colourful Unicorn Onesie

One design, two moods. This colourful unicorn onesie for adults comes as a two tone print, where hot pink and electric purple run diagonally across the body, or as a multicolour print that softens the same waves with white and mint. Both are printed on soft flannel and dusted with small white stars that catch the light as you move.

The print continues over the hood, which carries its own horn and a pair of ears, so the whole look holds together even with the sleeves rolled up. A zip runs the full length of the front for quick dressing, side pockets keep a phone within reach and the cut stays loose through the shoulders and legs.

Men’s Colourful Unicorn Onesie for anyone who refuses to pick one shade

Choosing an adult colourful unicorn onesie means choosing the boldest piece in the collection. The two tone version reads dramatic in photos, the multicolour version feels lighter and more pastel, and a group can happily mix the two prints in the same room.

This is the one to reach for when the evening has a theme. It stands out on stage at a party, survives a full night of dancing and still works as pyjamas the next morning. Pick your print and let the stars do the rest.

More prints to mix and match

The kids colourful unicorn onesie offers the same two prints for children, so a parent and child can wear opposite versions. The rainbow unicorn onesie spreads the colours into a full pastel gradient instead of bands. Compare every design 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.
