Who are called cosers?

A section of youth in Taiwan who dress up like Japanese animation characters are called cosers. They emulate not just the costumes but even the roles of the characters. Experts view this trend as a way in which these youths try to break out of strict traditions of Chinese society. The act of imitating these characters is called cosplay. The cosers exhibited their flamboyant sense of style during the recently held expo of Japanese manga animation in Taiwan.
