Cosplay

Cosplay short for "costume play" is a type of performance art whose participants outfit themselves, with often-elaborate costumes and accessories, as a specific character. Characters are usually sourced in various Japanese and East Asian media, including manga, anime, tokusatsu, comic books, graphic novels, video games, and fantasy movies. Other sources include performers from J-pop, J-rock, Visual Kei, fantasy music stories, novels, and objects from cyberspace or the real world that are unique and dramatic.
Cosplay participants or cosplayers form a subculture centered around wearing their costumes and reenacting scenes or inventing likely behavior inspired by their chosen sources. In some circles, the term cosplay has been broadened to include simply wearing a costume, without special consideration given to enacting characters in a performance context.
