The advent of digital technology made the distinction between nations and languages, time and space, and even between the real world and the virtual no longer relevant or important. Innovation of digital technology in the field of Fashion is digital clothing. The purpose of this study is to conduct a theoretical investigation on how digital clothing could actually be applied in the clothing industry. The significance of this study lies in the facts that the various utilization plans presented herein further enhance the recognition of the necessity of research on digital clothing and that this research provides a solid foundation for further empirical study in pattern making. The fields in the clothing industry in which digital clothing will prove to be applicable are as follows; an innovative manufacture process which increases productivity through utilization of 3D clothing simulation, the activation of online stores, mass-customization production of clothing, SNS (social networking services), and etc. These newly emerging fields are of particular interest concerning the utilization of digital clothing technology. Research of digital clothing needs to be complemented and if that is achieved, digital clothing will bring innovation to all fields in the entire clothing industry; design, production, marketing, promotion, and so much more.
