The purpose of this study is to prove that interchange is the a key factor in costume style changes through case analysis in costume culture interchange, and further, to assist in gaining understanding of costume style changes of the present and the future. Study findings show that the pattern of acceptance of costume interchange was mostly integration, though it was influenced by the method of transmission. The integration is a process in which a foreign costume culture is constructively mixed into the existing one, and a factor that changes the existing costume culture.
