The word "pre-expressivity" comes from theater anthropology. During performance, the looks and movements of actors and dancers give more priority to defining the character's character to the audience than their words. Extending to the concept of accessories, they also use precise signals to preferentially express the uniqueness of the individual visually. Pre-expressivity ® holds the initial concept in the design process, advocating the integration of "accessories" with the concept of "things" and the body. Through the experimental exploration of materials, it tells about self-identity, cultural inclusiveness, universe, ecology and other related propositions.
