The expressiveness of use is of focal interest in fashion design, which makes the perspective of act design important in learning/teaching. The objective of the project presented here was to introduce interaction design methods in fashion design teaching to make act design explicit throughout the different stages of the design process in a systematic manner; to develop a general workshop curriculum in experimental fashion design focusing on the expressiveness of wearing and use. A series of test workshops were implemented to provide a foundation for reflection and critical discussions. The main results, motivated by workshop evaluations, consist of theoretical models for a systematic development of workshop exercises in fashion design aesthetics.
