A fetish in which sexual arousal depends on dressing as, or being with someone dressed as, a specific fictional character, archetype, or pop culture figure. The costume itself, the act of transformation, and the roleplay that follows are all part of what makes it arousing.
Many people into cosplay fetish are drawn to the gap between the performer and the character: the deliberate presentation, the ritual of suiting up, and the shared fantasy of becoming someone else for a while. It overlaps heavily with costume play, roleplay, and character-based dynamics, and often shows up in photo shoots, private scenes, or convention-adjacent meetups between consenting partners.
Worth knowing: Because scenes often involve elaborate costumes and assumed identities, agree in advance on limits, a safeword that works even while in character, and a clear plan for coming back out of the role afterward.
Also called: cosplay play, character play, costume fetish, crossplay, fursuiting, mascot play, superhero roleplay, anime roleplay
