Answer and Explanation:
Character chosen: Daisy Buchanan, from the novel "The Great Gatsby"
Costume: since Daisy is a wealthy young woman living through the roaring 1920's, her dresses would be mostly light-colored during the day, and extravagantly sparkly for the night. They would be knee-length, loose fitting, with a low waist, and mostly short-sleeved. She would wear heels, colors changing according to the dress. Her short hair would be arranged in tight waves.
