The house banners are up, the candles are lit, and you walk in wearing green and black. This Harry Potter Slytherin deluxe costume kit for adults brings the most ambitious house at Hogwarts to Halloween, cosplay events and fan gatherings, with a hooded robe, a tie and a scarf that already match.
The black robe has a pointed hood, wide sleeves and an open front, and every move flashes its bright emerald green lining. A Slytherin snake crest sits on the chest, and a toggle-style clasp fastens it at the front, so your house is clear from across the room. The green tie carries diagonal silver and white stripes and measures 57 inches long. The matching green scarf has light grey striped ends and its own crest.
Hosting a wizarding night? Serve drinks in a Harry Potter favour cup, set out treats on Harry Potter dessert paper plates and share some Harry Potter Bertie Bott's with your bravest guests.
Layer the robe over a white shirt and grey sweater for a student-inspired outfit. Tie a neat Windsor knot for prefect polish, or wear it loose for an after-class feel, then wrap the scarf around your neck. Made for adults of all genders, this Slytherin costume kit suits couples and friend groups sorting themselves into houses. Ready to join the serpents?
