Regardless which incarnation of the Doctor is your favorite, there is one thing that has remained constant through the entire series, the Tardis. This costume t-shirt resembles the police call box, which is actually the vehicle in which the Doctor and his companions travel through time. Trust us, it's bigger on the inside. Wear this Doctor Who Tardis Costume shirt to disguise yourself in hopes of attracting the Doctor. It's possible that he'll try to put his key in your lock and get inside you, but remind him that you're not actually the box he's looking for. You just want to be his companion.
