Harry Potter Costumes

Harry Potter costumes cover the full Hogwarts look for kids and adults. Most outfits build from one recognisable piece, a house robe, a striped scarf and tie in your house colours, then round glasses and a wand to finish. Pick your house, start with the robe, and add the accessories that make the character.

Harry Potter costumes for kids

The films are a World Book Day staple, so a robe-and-scarf combo works for the classroom and the party alike. Kids only need the house colours to be instantly recognisable as Harry, Hermione or Ron. Browse the World Book Day costumes for school-ready options.

House robes, scarves and wands

Most looks start with the robe, then the scarf and tie in your house colours, round glasses and a wand. Buy the pieces separately to build your own, or pick a full character costume to keep it simple. Add a Gryffindor red-and-gold or Slytherin green-and-silver scarf to lock in the house.

Group and family Harry Potter costumes

A whole house or a family of witches and wizards is an easy group theme, because everyone wears the same robe with a different scarf. Split the houses between friends for a photo-friendly set. See more group fancy dress ideas.
