“Cosplay (コスプレ kosupure?), short for “costume play“, is an activity in which participants wear costumes and accessories to represent a specific character or idea from a work of fiction.
Favorite sources include manga, anime, comic books, video games, and films. Any entity from the real or virtual world that lends itself to dramatic interpretation may be taken up as a subject”. ( This info. is come from Google)
(These cosplayers are wearing costumes inspired from the Bleach, anime.)
