Wizards are able to use their wand as a flashlight or to repel nasty Derailers, but to protect themselves from the cold, nothing beats a beautiful scarf in the colours of their house. Gryffindor for Harry Potter, Slytherin for Voldemort, Hufflepuff for Newt Scamander and Ravenclaw for Luna Lovegood, choose your side against winter. Stupefy!
