For all their short comings, the House Slytherin is a pretty tempting target to dress up as every Halloween. The Adult Harry Potter Slytherin Robe is exactly what every ambitious, wizard, warlock, or witch needs if they're going to dress up as a student of Hogwarts. You don't have to be a pure-blooded magician to see the appealing side of magician supremacy.
The world needs a bad guy and the Adult Harry Potter Slytherin Robe is just the costume to meet that need. Just as long as you aren't a sniveling punk like that Draco Malfoy kid. That one's always getting on my nerves. The Adult Harry Potter Slytherin Robe is just the item that an ambitious witch or wizard needs for this Halloween, comic con, or any kind of premiere.
