Dressing up as Harry Potter was the classic Halloween costume of the 2000s. You could either shell out a hundred bucks for an authentic Hogwarts wizard robe sold by Warner Brothers, or you could show up with the cheapest fake round glasses and a crude scar drawn on your forehead, which would work perfectly. I’m more interested in the niche Harry Potter characters one could dress up as back in the day. I would’ve loved to do a Professor Sprout illusion, but those costumes are difficult to come by. Being a patronus could be accessible if you had a cool blue animal costume with decorative streamers. If I were to go back to 2003, I would go as the feather that Hermione Leviosas off the table in Charms class. If you’re content with going as Harry, Ron or Hermione for Halloween in about seven months, these Harry Potter memes might expecto your patronum.
