This research identifies the types of relationship asymmetry within sustainable fashion supply chains and the role of relationship asymmetry in sustainable product development in fashion supply chains in the UK. This research that is based on supply chain experiences of experts highlighted that how relational asymmetries hinder sustainable product development in fashion supply chains, but also how sustainable behaviours, values and policies help to overcome the influence of relational asymmetry in sustainable product development process.
