A mane in every colour tops the Newborn Rainbow Unicorn Onesie

The rainbow unicorn onesie for babies is the brightest piece in the range and makes no apology for it. Pink, orange, green and blue run into one another across the flannel, sprinkled with white dots, while the hood adds a fluffy mane that follows the same spectrum from the horn to the neck.

A printed face sits at the front of the hood, with soft ears on either side and a long fluffy tail at the back that babies love to grab. The fabric stays light on the shoulders, so a full outfit of colour never turns into a heavy layer.

Infant Rainbow Unicorn Onesie for walks that end in a nap

As with every baby rainbow unicorn onesie in the collection, the zip runs the whole length of the front, which keeps a change quick even when baby has other plans. The cut allows a bodysuit underneath on a cold day.

It is also the outfit that gets the most attention at a family gathering, since the colours read from across the room. Keep it for a birthday, a first fancy dress or a pushchair walk that deserves a photo.

Colours for the whole family

A parent can wear the adult rainbow unicorn onesie and share the same pastel spectrum. For a calmer classic, the baby pink unicorn onesie keeps the design in a single shade. Compare every version 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.
