My aim with this study has been to examine how the fashion is a leading component in the novel The Picture of Dorian Gray. I have studied the role fashion plays in the novel and in which way it can be seen as a way of letting the reader know the important role of fashion in 19tcentury England and the morals of Oscar Wilde. To prove my thesis I have used literature that shows how Oscar Wilde uses influences from his own life in his writing of The Picture of Dorian Gray. I have also used Judith Butler's theory of performativity in analyzing the characters in ordet to display their way of staging themselves and their lifestyles and their dependence of that performativity in their interactions. Even though the theory of performativity often is used to hold the importance of the sexes, I have concluded that it has an important role in the novel when Dorian Gray interacts with the character Sibyl Vane who is an actress. My results have shown that fashion in the novel is often a way of letting the reader know important elements of a character in the way that certain fabrics and items are mentioned when Wilde writes about his characters. I have also found that fashion is an important factor when the characters judge each when they speak about the way they dress. The way fashion is presented in the novel is important to my thesis and has shown me how fashion can be used in literature as symbolic elements guiding the narrative.
