A lot of people find cosplays fun. The word “cosplay” is a Japanese contraction for the term “costume play”, where participants don costumes and dress up to look like characters from anime, from video and roleplaying games, from fantasy and science fiction stories, and sometimes from live action programs. In Japan, some people who engage in cosplays dress up as a popular J-pop (Japanese pop) or J-rock (Japanese rock) artist.
Most anime and comics conventions have cosplay events worked into their program to cater to people who love doing cosplay. There is no real point to cosplay; people dress up as their favorite characters simply for the sake of dressing up as them.
When they gather at cosplay events, they spend most of their time showing off in their detailed and elaborate costumes, check out the costumes worn by the other participants, and to take pictures. Cosplay events are fun events, even if they are wacky, outrageous, and sometimes downright weird.
