Crafted for the ladies, the 100% cotton Doctor Who Silence Tally Marks Women's T-Shirt is a fitted blue t-shirt displaying the Doctor Who logo and several tally marks. You see, the tally marks are for keeping tabs on the 'Silence', a group of aliens that are able to erase themselves from people's minds as long as they are no longer looking at them...which is probably advantageous to the rest of us because they are kind of freaky! The Doctor Who Silence Tally Marks Women's T-Shirt...wait, who were we talking about?
