This study examines the knowledge and involvement of consumers in sustainability goals, aiming to provide valuable insights to the textiles and clothing industry to foster their social responsibility efforts and enhance consumer interaction. By comprehending and monitoring consumer behavior, organizations can effectively implement sustainable practices and work towards achieving sustainable development goals. For this study, a questionnaire was designed to evaluate consumer concerns, behavior, self-reliance, and perspectives across four key phases of interest in sustainable consumer behavior regarding textiles—acquisition, use, maintenance, and disposal. The results show a compelling insight into the mindset of participants who prioritize budget, quality, comfort, and functionality over sustainability when acquiring new textile items. Most respondents do not participate in clothing rental or sharing and predominantly refrain from purchasing second-hand products, but they expressed a readiness to extend the lifespan of their products and displayed concern about ensuring a responsible end-of-life for their belongings. Moreover, they attach importance to textile products’ social and informational attributes and demand transparency from brands. These valuable data can guide the industry in its interactions with consumers. Scholars are increasingly committed to sustainability and its implications for practical application and policy development.
