Product description
The Star Unicorn Critter Onesie in big-kid sizes: a thick flannel jumpsuit with the full animal hood, for children 100 to 140 cm tall.

The Star Unicorn design
The unicorn's single horn was once believed to neutralise poison, which made 'unicorn horn' a prized object in medieval Europe. A starry unicorn for birthday parties and fantasy dress-up.

Dress-up that gets worn again
A costume that is also comfortable is the one that comes out of the drawer after the party. Thick flannel and a roomy cut make this one a weekend-morning favourite as much as a costume.

Sized by height
Pick the size that matches your child's height: 100 cm through 140 cm. If they are between two, go up — it is a loose, relaxed fit by design.

Frequently asked questions
Which size should I order?
Match the size to your child's height in centimetres — a 115 cm child takes the 120. Between sizes, go up.
How do I wash it?
Machine wash cold, inside out, and let it dry flat or tumble on low.
Can my child sleep in it?
No. It is a costume and loungewear, not sleepwear. It is a loose, hooded plush garment; children should sleep in close-fitting sleepwear with nothing near the face. Take it off before naps and bedtime, and keep an eye on a baby in it so they do not overheat.
How long does delivery take?
Orders are confirmed and processed within 4–5 business days, then typically arrive within 6–10 business days (US, UK, Germany, the rest of Europe and other countries) or 8–15 business days (Canada and Mexico), tracked to your door. Shipping is free.
