Have you always known you're a witch or wizard at heart? Well, shed your muggle-ness for an evening of holiday celebration and magic at your local Barnes and Noble for the Harry Potter Magical Holiday Ball.

Barnes and Noble locations across the country will hold a Yule-ball inspired dance party at all stores in the U.S. on Friday, Dec. 9 from 7-9 p.m. Muggles of all ages are welcome to join in on the holiday fun. 

Whether you want to come in your best-dressed, as your favorite Potter character or in your Hogwarts uniform, there will be festive activities to celebrate all things Potter.

Because of the obvious popularity of this free event, Barnes and Noble said customers should call their local store ahead of time for capacity limits or special instructions.
