Contemporary cosplay generally targets animation, manga, games, video games, light novels, movies, albums, special photos, idol groups, occupations, historical stories, social stories, or other self-created tangible characters, and deliberately wears similar costumes. Coupled with the matching of props, makeup, body language and other parameters, it is played into a "lived" role with manpower. https://www.ccosplay.com/
Another type of Cosplay is mainly to anthropomorphize non-human animals, military weapons, vehicles, civil infrastructure, operating systems, websites, etc., instill a soul with wisdom, and use corresponding costumes, props, makeup, body language, etc. To present these anthropomorphic characters, one of the common methods is to appear in a cute anthropomorphic form.
Cosplay is not a child's thing, perhaps because it is close to animation, people have misunderstanding. However, in Japan, one of the three films in the cinema will be an animated cartoon, among which there are many works that we are familiar with, such as Detective Conan, Crayon Shinchan, Slam Dunk Master, etc., and those who watch animated films can say that they are from 0 to 99 years old responsibly. As long as you think about it carefully, cosplay is a drama or musical.
