Costume designer Ha Nguyen also demonstrates this contrast in the clothing of the cast. The film starts with the prisoners having their clothing divided by ethnicity, with African Americans wearing different headwear, Latinos wearing vests and various arm accessories, and the White Americans in cut-off T-shirts. After the arrival of General Irwin, the prisoners start wearing more similar clothing in a "sharp military manner". The uniforms of the prisoners change from the usual chocolate brown color to light grey, because of its muddled look on film and excessive darkness in some scenes. Ha Nguyen also contrasted the non-battlefield ribbons found on Colonel Winter's uniform with the battlefield medals found on General Irwin's uniform (seen only in the opening scene as Irwin is inducted into the prison).
