This research focuses on developing a new clothing selection education system by using a Buddhist psychological perspective and a system approach to enhance clothing longevity and address the environmental impact caused by the fashion industry. By deepening wearers’ self-understanding, this system aims to encourage them to select clothing that “genuinely” suits them, rather than what they “believe” suits them—choices often influenced by external factors such as trends. This approach will promote a new form of consumption by shifting away from short-term usage-driven consumer behavior and offer a novel perspective that provides new insights into conventional Western viewpoints.
