Firstly, we can clearly see her desire for sex destroying her normal life. Blanche DuBois. Reared in Old South aristocratic traditions, she lived elegantly in the family homestead, married a man she adored, and pursued a career as an English teacher. But her life fell apart when she discovered that her husband, Allen Grey, was having a homosexual affair. Disgraced, he killed himself. Blanche sought comfort in the arms of other men, many men. Her desire is abnormal. Blanche even gets mixed up with a seventeen-year-old boy, which results in her being kicked out of the school and the town. When she meets Stanley for the first time, she lures him dubiously without caring that Stanley is her brother-in law. What’ more, when the young man collecting for the newspaper drops by, she seduces him to drink and then to kiss her. The desire always follows her. Maybe she’s hunting for some protection, or maybe the blood in her body renders her to response to her ancestors in terms of being an epic fornicator. We can regard it as the humanity, but we have to recognize that this woman is lost in this malice desire which eventually put her whole life into the hell.
Secondly, Blanche seeks for the elegant and decent life. She employs in her pursuit of what is magical and idealized. Blanche says “I don’t want realism, I want magic.” a paper lampshade with which she covers the harsh white light bulb in the living room; her chronically deceptive recounting of her last years in Belle Reve; the misleading letters she presumes to write to Shep Huntleigh; and a pronounced tendency toward excessive consumption of alcohol. Blanche creates her own fantasy world through the characters she plays, such as the damsel, southern belle or school teacher. She wears her costumes to create a fa?ade to hide behind, concealing her secrets and attempting to reach her former glory, and illustrating her inability to relate to others in a “normal” Blanche is wearing white clothing and gloves, as well as pearl earrings, when she arrives in New Orleans to suggest that she has a pristine character. However, she prefers darkness and shadows to mask her physical perfections and, symbolically, her. Blanche quotes poetry and speaks the elegant patois of aristocrats. Though scarred by her past, Blanche still tries to lead the life of an elegant lady and does her best, even lying when necessary, to keep up appearances.
