Alice Walker is an outstanding black woman writer in American literature, whose masterpiece is a novel, The Color Purple. In The Color Purple, Walker describes a tough course in which the protagonist, Celie, is from suffering repression to achieving independence and liberation. Moreover, the novel reveals that the black women, who are under the double oppressions of racialism and sexism, pursue self-independence and self-development in order to achieve gender equality and racial equality. Through careful interpretation of Celie''s changing costume, readers can analyze Celie''s psychical growth process which is from numbness to awakening, and eventually to independence. By means of researching, it can draw a conclusion that costume in the novel is not only used to do covering, to escape coldness or to beautify Celie, but also a kind of expression to show her inner world, personality as well as living style. Thus costume is a silent language and mark in a pure state.
