Fashion 5.0 represents the next phase of digital transformation in fashion supply chains, integrating Artificial Intelligence (AI), the Internet of Things (IoT), blockchain, digital twins, and cyber-physical systems to enhance sustainability, resilience, and transparency. While research on digitalization and sustainability in supply chains is expanding, the synergistic role of these technologies remains underexplored. This paper conducts a bibliometric and trend analysis to identify key research areas, gaps, and technological enablers shaping Fashion 5.0. Findings reveal that while AI, IoT, and automation are widely studied, their application in adaptive, real-time decision-making and self-regulating supply networks is still emerging. Blockchain is primarily examined for traceability and compliance but is not fully integrated with circular economy models or AI-driven optimization. The study proposes a technology-driven maturity model as a strategic framework for advancing digital, intelligent, and sustainable supply chains in the era of Fashion 5.0.
