Description

A unicorn onesie for adults who refuse to grow up - and we respect that. This one features the iconic rainbow fish-scale pattern in full color: red, orange, yellow, green, blue, and purple scallops layer across the polyester flannel body. A large white belly panel and white zipper area create visual balance. The hooded top has a bright yellow horn, pink ears, and embroidered unicorn eyes.

Details That Matter

Front zipper closure with deep pockets. Sizes from kids (height 95cm) to adult XL (188cm), though this one looks particularly good in adult sizes where the scale pattern gets the room it needs to breathe. The flannel is lightweight and warm, perfect for heated homes where heavy fleece would be overkill. Browse the rest of the Unicorn Onesies collection for more options. The body runs relaxed through the torso for unrestricted movement overnight.

A Unicorn Costume accessory takes this from pajamas to party-ready. The Scale Pajama Onesie has the same pattern with a parent-child matching option.
