It's not easy to run a secret student club at Hogwarts, especially with Dolores Umbridge in charge. But with Lord Voldemort's return on the horizon, Harry Potter and the members of Dumbledore's Army do what they have to. You can sign on with Harry's band of rebels with this stylish black T-shirt, featuring the D.A.'s logo and its members' signatures. Just don't let Umbridge catch you wearing it! This shirt is available in adult sizes.
