On The Big Bang Theory, Penny (played by Kaley Cuoco) is the catalyst of the entire series when she moves in across the hall from Sheldon and his roommate Leonard, her eventual husband.  Penny's clothing changes a lot throughout the 12 seasons, which mirrors her career movements as well.  Some of her most iconic clothing includes her Cheesecake Factory uniform, the daisy dukes shorts and pink tops she is known for in the early seasons while she is trying to become an actress, and her pink business suit from the series finale after she has established herself as a successful sales rep at a pharmaceutical company.
