Many apparel designers were approached in collaboration of the film's costumes. The Great Gatsby achieved the iconic 1920s look by altering pieces from the Prada and Miu Miu fashion archives. Martin also collaborated with Brooks Brothers for the costumes worn by the male cast members and extras. Tiffany & Co. provided the jewelry for the film. Catherine Martin and Miuccia Prada were behind the wardrobe and worked closely together to create pieces with "the European flair that was emerging amongst the aristocratic East Coast crowds in the 1920s"
