PRODUCT DETAILS
What's in the Box
- Black hooded robe with emerald green lining and serpent house crest
This Kids Slytherin Robe Costume brings the ambitious wizarding house to life with an ankle-length black cloak trimmed in signature emerald green. The serpent crest sits proudly on the chest, and the lined hood drapes perfectly for that dramatic entrance into the Great Hall.
The green satin lining flows from the hood down both front edges, creating a bold flash of house colour when your child moves. Open-front design means it slips on in seconds over jeans and a white shirt — no fiddly buttons or zips to wrestle with before the costume parade bell rings.
Perfect For
Book Week & Literature Days: A natural choice for Harry Potter-themed Book Week, wizard character parades, or any school dress-up day celebrating fantasy literature and magical adventures.
Halloween & Costume Parties: Ideal for trick-or-treating, wizard-themed birthday parties, Halloween events, or any costume occasion where your child wants to represent the cunning house with pride.
Dress-Up Play at Home: Perfect for imaginative play, re-enacting favourite scenes from the books, or creating magical adventures in your own living room with friends.
How to Wear It
Wear over a white button-up shirt and dark trousers for the full school uniform look. Add a house-themed tie, wand, and striped socks (sold separately) to complete the ensemble. Comfortable sneakers or black school shoes work perfectly underneath.
Parent FAQs
What size should I order?
Check the size chart for chest and length measurements. The robe is designed to hang loose and long, so if your child is between sizes, the smaller size usually works fine — it's meant to be floor-skimming rather than fitted.
Can they wear this over their school uniform?
Absolutely. The open-front design means it goes straight on over whatever they're already wearing — perfect for Book Week morning when you're racing out the door.
How do I wash this? Will the crest peel off?
Hand wash in cold water and hang to dry, or gentle machine cycle inside a pillowcase. The heat-transfer crest is durable but avoid high heat to keep it looking sharp.
Is this suitable for outdoor Halloween trick-or-treating?
Yes — the ankle-length design provides good coverage, and the hood keeps the chill off. Just make sure they wear warm layers underneath if it's a cold night, as the fabric is lightweight polyester.
Care: Hand wash cold or gentle cycle; hang to dry, avoid high heat.
