I have a really cool one! I'm going to the party the company is throwing in one of the hangars at the airport.
I got a traditional checkered Arab headress, a nasty old wool robe that comes calf length, sandals, a well-used Sryian army battle jacket and a belt of about 20 road flares with wires, batteries and a big red button on it.
I'm going as a Peacemaker.
