Recently in the post-modernism era ethnic look tropical look or ecological look has prevailed as an important theme of fashion all over the world. The main core of these themes is based on primitivism. The purpose of this study was first to com-prehend the internal meaning and the exteral form of primitivism in modern fashion second to compare the characteristics of primitivism in art with those in modern fashion as one of the phenomena in cultural consistency. For this purpose documentary studies about primitivism in social science and art were preceded as a framework of this study and then objective studies about primitivism in modern fashion and art were analyzed. Primi-tivism expressed in clothing since the 16th century was also historically traced. the results were as follows: 1. Primitivism in modern fashion was summarized by emotionality play ecology and aboriginality as well as was represented by ex-ternal forms of open form part-to-whole re-lation planar intergration rounded form and indeterminate form It was demonstrated that the external form of primitivism in art and fashion is quite similar and is an example of cultural consistency. So it is reaffirmed that fashion is the production of culture representing zeitgeist as a genre of art. 2, Modernism in the early 20th century brought the richness of materials through the de-velopment of the mechanical culture emphasizing rationality as well as functionalism, Fashion also has been influenced by this modern-ism so it has tended to express only the beauty which emphasizes the functional aspects of clothing and excludes the decorative characters. The primitivism in recent fashion is against the flow of modernism. In a word the pursuit for the regression to nature and the recovering of hu-manity is the core of the primitivism in modern fashion.
