You'd better be sure you're not a muggle before wearing the deluxe Hogwarts student witch hat with our Harry Potter costumes! The black hat is made from a velvet material and has a size adjuster on the inside that measures between a 17" and 22" circumference. It has a wire rim and features an embroidered gold Hogwarts logo with a black "H" on the front. Add a wand to your look from our Harry Potter accessories and with any of our Harry Potter costumes, you'll be casting spells by Halloween!
