This paper analyzes the parallelism between the art trend and the fashion. As a representative case, we consider the Modernism and the Flapper look. The Modernism rejected the tradition of the past and pursued something new. This trend was in parallel with the fashion called flapper look which was against the tradition and made drastic change. The factors which represent the spirit of the age the Modernism are the simplicity, the rejection of the tradition, the individualism and the subjectivity, the functionalism, the fragmentation of the self, and the straight line. We discuss the fashion style of the flapper look in terms of these factors.
