Abstract The fashion industry is under increasing pressure to adopt sustainable practices due to the high levels of waste and environmental impact generated by traditional prototyping and production processes. Digital Twin Technology (DTT) offers a transformative solution by creating a virtual replica of garments and manufacturing systems that enables real-time simulation and optimization before physical production. This paper explores how digital twin systems can be integrated into the fashion prototyping process to reduce material waste, improve design efficiency, and promote sustainability. Through a conceptual framework and simulation-based analysis, the study demonstrates that digital twins can significantly minimize fabric usage, shorten design cycles, and enhance collaboration between design and manufacturing teams. The findings confirm that adopting digital twin technology can support circular fashion initiatives and align the apparel industry with the principles of sustainable development.
