In The Wizard of Oz, the costumes bring the magical world of Oz to life with vibrant designs. Dorothy’s blue gingham dress contrasts with the Tin Man’s shiny metallic look and the Cowardly Lion’s furry ensemble. The Wicked Witch’s dark attire and Glinda’s sparkling gown highlight the contrast between good and evil. These colourful costumes enhance the musical’s whimsical atmosphere and themes of courage, friendship, and home.
