Using a range of interpretive methods, including focus-group interviews, in-depth interviews, and structured field observations, this study investigates how shopping experiences within sustainable fashion stores may cause consumers to change their attitudes towards sustainable fashion. Heider’s balance theory was applied to interpret the results, whereby we constructed the maps of individual consumers’ positive and negative associations of concepts, events, and outcomes within consumers’ purchasing decisions about sustainable fashion products. Our findings suggest that there could often be a gap between the consumer’s perception of sustainable fashion and their actual purchase behavior, which creates an ‘imbalanced’ state. However, positive store experiences may persuade consumers to achieve a balance by purchasing sustainable fashion products. The study provides important and theoretical and practical insights for sustainable fashion marketing
