AbstractWhere clothing consumption has continued to rise around the world, a deeper understanding of how and why garments are disposed of is critical in regard to addressing the issue of textile waste by consumers. The purpose of this study was to explore the garment management processes of young, fashion sensitive consumers, examining their disposal behaviours as well as motivations towards garment end‐of‐life extension through maintenance or repair of damaged fashion clothing. A survey of 161 South Korean young consumers (18–34 years) was conducted, utilizing a fashion sensitivity scale to measure impact on unsustainable garment disposal practices and garment repair behaviour. Further, general recycling behaviour of these individuals was examined, as linked to garment repair propensity. Results indicate that fashion sensitive consumers dispose of garments more rapidly, and with less ethical consideration. However, these same consumers are motivated to repair items that support their fashion identity. The study contributes some useful insight into encouraging garment life extension practise among heavy consumers of fashion, thus extending what is known about fashion garment disposal in the sustainability context.
