Abstract: To carry forward traditional costume culture, a Kinect-based 3D costume culture display system was designed based on somatosensory interactive technology and Augmented Reality （AR） technology.Different from virtual mirror for commercial use, the system pays more attention to the popularization of Chinese traditional costume culture. The costumes, which are displayed under several themes such as Ancient Costumes, Ethnic Costumes and Costumes for the Olympic Games, would give viewers a completely new experience.
