Abstract
Post-structuralism in Fashion tendency since the late 20th century has been developing in complicated and diverse modes. Post-structuralism has revealed the inconsistency of Western philosophy contering on rationalism, and has formed an important thought system of modern time through open thinking and various ways of expression. Among them, decentering which is formed from the concern for outlying 'others' while denying self-centered 'man himself, has supplied a new cognizance paradigm in the expression and interpretation of fashion formation. This paper has analyzed the expression-form of fashion in three ways: de-construction, discontinuance, and esthetic appreciation of the others. Finarly this study has supplyed, though decentering thinking, a new esthetic cognizance principle for fashion which is expressed in free and multiple meaning and form.
