Two or more characters wearing each other's default clothes.
Never use this tag if there is only one character in the image who happens to wear another character's clothes or if one of the two characters in the image wears the other's clothes, but the other is still wearing his/her own clothes, especially one that is a duplicate of the cosplay; use cosplay instead, if that tag is absent.
Also "*_(cosplay)" tags are not necessary since it is obvious the two charcters are "cosplaying" each other. However those tags can be added for reference at one's own discretion.
The following tags are aliased to this tag: exchanging_clothes and costume_swap (learn more).
This tag implicates cosplay (learn more).
