Geekosystem has more on the first official Tetris costumes and how they’ve already been banned from one London bar because people would come in wearing them so they could reserve space for their friends. As Geeko points out, the “ban” is almost absolutely a publicity stunt engineered by Morph Costume Co., which makes the costumes. But I don’t care. The image of people wearing these in line at con panels so they can save room for friends unwilling to spend the required amount of time waiting is dancing before my eyeballs.
Nobody do that.
