Show off your geekiness yet still conform to your company’s outdated office dress policy with these Harry Potter House Ties (because you’ll probably get fired if you show up in the wizard hat- again). Shows off the coat of arms and colors for the respective houses. Are you a Gryffindor, Slytherin, Ravenclaw, or Hufflepuff? Hopefully not a Hufflepuff, since that one’s backordered a few weeks (who knew it was so popular?) Made of 100% silk and 75% geek. $19.99 each.
