Julian, a writer with writer's block, finds inspiration by wearing his fiancée Olivia's clothes and props, creating a female muse/persona named "Juliet." This deepens, and he becomes obsessed, dressing as Juliet more frequently and in public, which strains his relationship with Olivia. Olivia struggles with his immersion but tries to be supportive. After a confrontation, Julian attempts to find balance. He finishes his novel, and his agent/publisher are excited. He wants his author photo to reflect Juliet. They eventually find a healthier balance, with Julian integrating Juliet into his life more moderately, and their relationship strengthens, leading to their wedding where he wears a blended outfit.
