Planet of the Apes
Wear a Planet of the Apes costume when you take over the world. In the not so distant future, mankind is all but wiped out by a man-made disease while apes with scientifically enhanced intelligence assume control of the planet. Be on the winning side by transforming yourself into one of the apes. If you're a fan of the original movies from the late 60s and 70s, the 2001 remake by Tim Burton, or the latest reboots, you're in luck.
There are ape outfits you can wear to any costume party. The chimpanzees, gorillas, and orangutans in the Planet of the Apes movies don't look like the apes of today's world. They have more human physiques, although with distinctively ape-like faces. The three types of apes also play different roles in their society. The chimps are scientists and intellectuals, the orangutans make up the government, and the gorillas are the police and military.
There are masks and costumes for some of the characters from the Planet of the Apes movies. It's also easy to create your own-a fun idea if you can't pick a favorite movie or character. The nice thing is you don't have to wear a full ape suit. Just pick an ape mask and maybe some ape hands and combine them with a sci-fi style outfit. Add accessories that fit the type of ape you are. If you wear a chimpanzee mask then get some doctor or scientist props and put on a lab coat. If you prefer a gorilla mask then you'll want something a little more military including a toy rifle.
