Even though I have started to dislike Olivia, I really love how her character is written and portrayed. In early seasons, her outfits were predominantly white. This represented her "white hat": It showed how she didn't fight dirty. In later seasons, her outfits started to be black with white highlights. It showed how she was starting to become her father and use more underhanded tactics. Eventually, her outfits became completely black. There was no more white in them, and Olivia no longer wore her white hat.
