As a long-time Harry Potter fan, it's been on my mind to make HP-inspired hoodies since the business started. These hoodies are my most customizable, with your option of any 2-digit number on the left arm and a choice of lettering in Defense Against the Dark Arts, Charms, Potions, and Quidditch.You can purchase yours here: www.RaritysBoutique.etsy.com and remember, you can customize your fit and size because it's custom-made for YOU!
