Online media have been going forward rapidly and have penetrated into various aspects of people＇ s life, thus having a significant impact on people＇ s production and life. Under such circumstance, traditional fashion indnstry has also been influenced by online media and has gradually transformed to digitalization. Fashion design is likely to get away from simplex manual design and to transform to the design method of man-machine synergy. The introduction of network technique into fashion design will bring vast potential for future development of fashion design.展开更多
