Just in time for undeadliest of holidays comes The Horde T-Shirt ($18). This black American Apparel tee sports a terrific print of a single character wielding multiple weapons on the roof of a car as a horde (get it?) of zombies surround him. While it won't pass as a costume per se, it's certainly festive, and if you happen to harbor a secret zombie obsession, you'll no doubt find yourself wearing it all year long.
