Final answer:
Dressing up has a substantial impact on the musical style by enhancing the stage presence and contributing to the audience's experience, which is exemplified by a show that tackled new themes and showcased a diverse cast.
Step-by-step explanation:
The impact of dressing up on the musical style of a production can be quite significant. Costumes and set design contribute to the audience's perception and experience of the performance. A striking example is a show that introduced new subject matters like cross-dressing, homosexuality, and other social issues, which were reflected in the storytelling and the diverse cast of characters.
Such artistic choices can enhance the stage presence of a performance by making it more visually appealing and engaging to the audience. Costumes and set design can underscore the seriousness, comicality, or realism of the actors’ delivery, thereby influencing the play's meaning.
