Leatherface, The Texas Chainsaw Massacre (1974)
Even though you'll have to leave the chainsaw at home, there is plenty to work with if you decide to dress up like this iconic killer maniac. Try sticking to the bloody wardrobe of the Gunnar Hansen original version if you want props from cinematic purists (white collared shirt and dark pants, jacket and tie, and maybe a mask made out of bacon).
Shé, Machete (2010) and Machete Kills (2013)
As the badass leader of a group of undocumented Mexican immigrants, you better be ready to flaunt your Latina pride as much as actress Michelle Rodriguez does in this role. All it takes are some long black boots, black pants, a black leather bra, a black eye patch and some black holsters to keep your weaponry locked and loaded. Drag around a Donald Trump piñata just for the hell of it.
