It's hard to be a Potter geek when your office dress code doesn't exactly encourage the wearing of robes. How does one communicate to other witches and wizards without offending the Muggles? It's as simple as putting on a very special tie.
If you'd like to stealthily dress as a Hogwarts student while at work, you'll need a house tie. These officially licensed neckties are made of silky 100% silk and feature the colors and coat of arms of the houses Gryffindor, Slytherin, Ravenclaw, or Hufflepuff.
