Doom/Quake t-shirts

I've looked online and on ebay for Quake and Doom shirts but have had little luck (Ebay does have a rather boring Quake shirt though). id's official website has a Doom 3 shirt in 3X, but since I'm not a raging fatass (I'm actually a small), it would obviously be too big for me. They also do not carry any shirts with the original logo on it. Does anyone know where I might find shirts of this nature? Or should I just simply ghetto-rig it and make my own?

Heh. Look Harder. It has the official DOOM symbol on it.
