A cosplayer is a person who wears costumes and accessories to represent a character for role-playing purposes. Cosplayers often gather at fan conventions in order to recreate the fictional world that they enjoy so much.
Cosplay has become more popular over the years as comic book movies and anime have become more widespread. It is especially prevalent in Asian cultures.
