In The Sound of Music, the costumes reflect the charm and simplicity of 1930s Austria. The von Trapp children’s school uniforms and the colourful dresses worn by Maria emphasize innocence and youth, while the more refined outfits of Captain von Trapp and the Baroness showcase social class. Maria’s iconic nun’s habit and later, her floral dress, symbolize her transformation and newfound freedom. The period-specific costumes enhance the musical’s warm, nostalgic atmosphere and the themes of love, family, and change.
