It should be COSPLAY. Cosplay is the abbreviation of English costume drama, and the verb is cos, and people who play cosplay are generally called coser [also called cosplayer]. Generally speaking, the earliest Chinese translation of cosplay came from Taiwan Province Province, which means role-playing. But because this translation is the same as the role-playing game (rpg) in the game, in order to avoid the similarity, the author prefers another translation-dressing up. As far as today's cosplay is concerned, its form and content generally refer to the use of clothing, trinkets, props and makeup to play the roles in acg (animation, comics, games) or some roles in Japanese Vision Rock and movies. Thus, cosplay contains a vast space for its positioning. It can even be said that as long as there is cosplayer, this field is definitely the mainstream of teen pop culture today.
