4. Ravenclaw Robe

Harry Potter Ravenclaw of Hogwarts Robe Costume

5. Slytherin Robe

Harry Potter Slytherin of Hogwarts Robe Costume

While Slytherin produced many of the worst wizards of all time (including the #1 big bad), it also gave us brave (albeit unbeknownst to us until much later) Snape and sharp-witted Slughorn. So, if the Sorting Hat pops you into the snake-whisperer’s house, wear your robe with pride!
