The purpose of this study is to present the enlargement of the area of the expression. Thish process takes steps as follows : 1)To inquiry the expressed examples in modern fashion through plasticizing the geometric cubic. 2) Through this process to sruvey the potential of the development inherent in fashion design possibility. 3) At the same time to establish the status of fashion as a part of the Plastic Art. This study is to re-illuminate the plasticity expressed in modern fashion. The result of this study testified that in the relation between fashion and the human body the plastic characteristics of geometric cubic enlarged the special three-dimension effect and in the connection of form and from there is a potential possibility of the way of organization in discovering and establishing the world of the new form through the temperate organization.
