Adopting a sustainable business model is an essential element of gaining competitive advantage. Specifically, the management of fashion and textile supply chains characterized by geographical extension requires paying particular attention to environmental and social sustainability. Following an analysis of the literature on sustainable supply chains in the fashion and textile industries, this qualitatively based research examines – from a supply chain perspective – the sustainability initiatives implemented by a yarn and garment producer through a single case study. Subsequently, the classification of potential sustainability initiatives is presented. From this investigation, several good practices for sustainable fashion supply chains can be identified, providing a reference point for similar companies. Keywords: sustainable fashion supply chain, sustainable textiles, closed loop supply chai
