What makes a costume real?

Costumes, cosplay, derivative imaginative experiences. When does a costume become real? Is a persona a mask? Can it become real? The pathway on the stage becomes real when the audience walks through it. How fiction can vibrate to the frequency of real. The audience decides that this is an enactment experience. We put on the costume and align with another form of being self. Synesthesia and the experience of becoming; self to character. Not necessarily synthesis. Derivative imaginative play. Solidly not real. Beyond the cover of the song. The notion of the influence. Costumes as a scaffolding technique of becoming as a creative.
