Second-hand fashion start-ups: innovative business models and their role in sustainability

The growing attention to sustainability and circular economy has made the fashion industry one of the most discussed sectors in terms of environmental and social impact. The second-hand fashion industry emerges as an innovative response to the inefficiencies of fast fashion, promoting waste reduction, extending product lifecycles, and material circularity. This research explores the innovative business models adopted by start-ups in the second-hand fashion sector, aiming to understand how these companies contribute to sustainability goals by integrating economic, environmental, and social aspects. The sample analyzed includes 11 start-ups, selected for their ability to innovate within the circular fashion context, using qualitative methods based on interviews and analysis of their digital platforms. The results show that these companies not only address issues related to textile waste and resource inefficiency but also promote social inclusion and economic resilience, contributing to a more responsible consumption model. The research is based on a theoretical foundation that integrates sustainable business strategies and circular economy models, offering an innovative perspective on business practices in a rapidly evolving sector. The findings of this research aim to enrich the debate on the potential of second-hand fashion in promoting the transition to a more equitable and responsible economy, while also providing practical insights for stakeholders across the textile industry.
