The costumes at LeakyCon, a Harry Potter fan convention in Dallas, were pretty spectacular.

Approximately 10,000 Harry Potter fans filed in to the Kay Bailey Hutchison Convention Center in downtown Dallas, all there to celebrate the J.K. Rowling books and movies telling the magical stories of a boy named Harry Potter and his fantasy wizard world.

A special guest at the 2019 LeakyCon in Dallas was Tom Felton, the actor who played wizard bully Draco Malfoy in the movies.  

LeakyCon is also expected to take place in Boston in late 2019 and Orlando in 2020. The fact that the convention returned to Dallas for a second year was big news for Muggles.

Attendees dressed up in costume, listened to Q-and-As, shopped for Harry Potter swag and convened with people in their Hogwarts House: Gryffindor, Slytherin, Hufflepuff or Ravenclaw. (Don't know which one you are? There's a quiz.)

Look inside LeakyCon in Dallas:

Serious fans went all out on their costumes.
