Instead of dressing up as Snape, you can replicate one of his less conventional outfits on Halloween.

In the “Harry Potter” universe, Boggarts are shape-shifting illusions that represent your biggest fear. Neville Longbottom’s Boggart, for example, is Professor Snape dressed in his grandmother’s clothes.
Last Halloween, Jamie Andrews replicated the look for his Halloween costume. You can do the same by utilizing a green skirt, tweed jacket, a bird-embellished hat, and an animal-shaped scarf.
