With the threat of the climate emergency intensifying and limited time left to reduce irreversible consequences, the need to consider how natural resources are excavated and managed from cradle to grave intensifies. This positions the circular economy (CE) as being highly relevant, particularly for the fashion industry, which is criticised for encouraging continued frequent and impulsive consumption of inexpensive garments with limited longevity. Advancing the circular fashion economy (CFE) has received little attention. Limited research to date has found that consumers have not been socialised to consider fashion acquisition as a collaborative or sharing activity, revealing an established attitude–behaviour gap that prohibits the advancement of the sustainable-fashion agenda. Primarily, fashion is imbued with social and emotional capital, as experienced with the dominant social paradigm (DSP) of fast fashion. This paper argues that similar tactics can be adopted for sustainable fashion practices through the CFE by exemplifying a case study of a fashion-renting platform, “Wardrobe,” that enables consumers to rent fashion owned by influencers and celebrities. In doing so, the paper makes four contributions to the knowledge: Firstly, in developing a conceptual framework from research examining fashion, sustainable fashion, and the CFE, the paper illuminates how fashion marketing emphasises social and celebrity capital to appeal to consumer emotions, encouraging frequent impulsive consumption, and how this can be transferred to the CFE. Secondly, the DSP is contextualised alongside the theory of disruptive innovation to understand how social norms of fashion consumption can be disrupted. Thirdly, although there is an emerging literature stream examining the CE and CFE, this focuses more on consumer practice and behaviours, and little attention has been paid to how the CFE can be marketed to engage with consumers. Fourthly, this paper illuminates how similar marketing tactics used by fast fashion can be exploited to advance the CFE.
