This work centers on the concept of digital costume and its embodied dimension within digital environments. It aims to explore the intersection of choreography and costume design through the lens of emerging technologies—specifically digital cloth simulation, motion capture, and extended reality (XR). The central objective is to examine how digital cloth animation can function not merely as a visualization aid, but as a generative, collaborative tool in performance- making. This study is grounded in the context of contemporary dance practices and unfolds through a discussion of the rationale, related work, research questions, methodology, and current progress.
