Cosplay Fan Art - Television Tropes & Idioms

This is a Sub Trope of, well, Fan Art, where the artists draws established characters dressing up as other established characters.

Note that this is extremely common, and some picture sites and Image Boards can have hundreds or thousands of pictures. Although searching isn't always reliable, given pictures can be tagged for things they don't fit, especially dirty pictures, which are not a good idea to link to on this site, even indirectly (it's not prudishness; it's about not setting off content filters).

We humbly suggest you reserve examples to these conditions. You don't have to, but it's a way to keep examples from getting out of hand, and to avoid links that are Not Safe for Work.

Know who the characters are.
Know who they are dressed as.
Provide a link, because of course some of us would want to see this.
If the link requires dragging and dropping, please let us know.

Halloween Cosplay is actually a Sub Trope of this, because that is of course just for Halloween. Webcomic authors will also sometimes utilize this for Filler Strips, which qualifies if it's a Guest Strip, but it often isn't.

Despite the name, this can be official. See Side Story Bonus Art.

Compare Clothing Switch, Whole Costume Reference.

Not to be confused with Fan Art about Cosplayers.
