This Harry Potter robe costume for kids is not only easy to wear and simple in appearance but the most recognizable costume there is. As long as you have the robe with the school emblem on the left side of the chest, then you’re pretty much all set for this costume. If you really want the complete Harry Potter look, then make sure to get a scarlet and gold scarf, or the Hogwarts scarf. If you want the more mature look, then you could go with the scarlet and gold Gryffindor tie. Just be sure to wear a nice and crisp white dress shirt underneath your robe and you’ll be all set for Halloween! You can even throw in a Harry Potter wand or the Harry Potter glasses if you’d like.
