Product description
The White Unicorn Critter Onesie turns a soft flannel romper into an animal: a character hood, a soft tummy panel and a zip down the front — sized for babies and toddlers from 56 to 110 cm.

The White Unicorn design
The unicorn appears in stories from ancient Greece to medieval Europe and is Scotland's national animal. A soft white unicorn for birthdays and fairy-tale photos.

The hood is the character
Each design is built into the hood — ears, horns, spines or fins stitched in place — so the animal reads from every angle, and the body stays a simple romper underneath.

Easy on, easy off
A zip runs down the front, which is what makes a costume usable on a wriggling baby: open it, change them, zip it back up.

Frequently asked questions
Which size should I order?
Go by height. Size 70 fits 56–66 cm, 80 fits 66–70 cm, 90 fits 70–80 cm, 100 fits 80–90 cm, 110 fits 90–100 cm and 120 fits 100–110 cm. Between two sizes, take the larger — it leaves room for a layer underneath.
What is it made of?
100% polyester flannel, including the hood. Machine wash cold, inside out, and zip it up first.
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.
Is shipping free?
Yes, on every order of $29 or more. Below that, standard shipping is a flat $9.99, shown at checkout before you pay.
What is your return policy?
You have 30 days from delivery to return an unopened, unused item in its original, undamaged packaging — no reason needed. Email us your order number first and we reply with the return address; return postage is paid by you and shipping charges are not refunded. If an item arrives damaged, faulty or wrong, contact us and we take it back at our cost. The refund goes out within 3 business days of the return reaching us.
Is there a warranty?
