Andrea knows nothing about fashion and people at the magazine makes fun of her. Throughout the film, her sense of style changes and she becomes a true fashionista. But as everything comes with a price, her relationships with friends and boyfriend starts falling apart. At the end of the movie, Andy understands that life is made of hard choices and she needs to go after what she wants.
This movie represents the fashion industry as a world full of narcissistic and shallow people. An example is the way that everyone at Runway Magazine starts treating Andy differently when she decides to dress “accordingly”. She became respected by Emily, the first Assistant, and only after the makeover that she started to get thinks right that Miranda asked her. The fact is that the movie emphasizes the change of her behavior on the fact that she gave in into the fashion world, but the truth is that she changed her perspective and decided to have a positive attitude towards the things she needed to do.
To create this high fashion atmosphere, the use of costuming is indispensable. As Stutesman would argue, “[costume] must express something far beyond the outfit: the costume designer must use clothes to create basic movie elements” (Stutesman 20). If the right clothes were not used, then the movie would not make as much sense, or it would not make the same impact as it did when it first came out.
