British costume designer Ruth Myers created and designed the clothing for the film. She wanted to mirror the lightness of the script within the costumes and give "a spark of color and life" to the early 19th century setting. During her research, Myers noted a similarity between the fashions after the Napoleonic Wars and the 1920s, saying that they had "the same sort of flapperish quality". The designer explained "The moment I set to research it, more and more it kept striking me what the similarities were between the two periods. It was a period of freedom of costume for women, and it was a period of constant diversions for the upper classes–picnics, dinners, balls, dances. What I wanted to do was make it look like the watercolors of the period, which are very bright and very clear, with very specific colors."
