Canon-accurate

Canon-accurate describes a costume that matches a character's official appearance as closely as possible, making it a key goal for many cosplayers.

A canon-accurate costume is one built to reflect exactly how a character looks in their original source material — whether that is a video game, animated series, film, comic, or other official work. The aim is to match colours, silhouette, textures, and small details such as buckles, insignia, or trim as faithfully as the maker can manage, using the official art or production stills as the reference rather than fan interpretations or merchandise. Achieving this usually means gathering multiple reference images from different angles before you cut a single piece of fabric or foam. Keep in mind that source material itself sometimes changes between adaptations, so it helps to decide which specific version — a particular game release, a season of a show, or an issue of a comic — you are treating as your authority, and to note that clearly if you enter competitions where judging criteria may ask about it.
