The application of deconstruction in fashion is an interesting phenomenon of debate. Thisresearch traces the origin of deconstruction and examines how fashion in the postmodern societycorresponds to the deconstruction philosophy proposed in 1966 by French scholar Jacques Derrida. Through the study on fashion deslgners practicing deconstruction ideology, it is discovered that in search of novelty,deconstruction fashion deslgners challenge absolute truth andprmciples built by the traditional fashion society, and hence, transform their design process intoone that honors skepticism and deconstruction of set rules. Second, by inquiring the socialfunctions that adhere to existing style, material, form, and symbol, deconstruction designersform personal style, logic, and aesthetic taste to support their design. Third, the course of suchinquisition parallels the deconstruction thinking of Derrida, which boldly brings to surface theintention to tactically redefine fashion, to analyze the relationship between an outfit and the body, and to study the underlying cultural ideology of fashion.
