This study aims to understand the dimensions associated with the behavior of the Slow Fashion consumer, their values, attitudes, and motivations, as well as to know in depth the literature related to Slow Fashion. The present article is a literature review related to the concept of “Slow Fashion”, and follows a qualitative methodology based on an in-depth literature review of 25 papers from the Scopus and Web of Science research databases. For this literature review, a content analysis was initially performed through a bibliometric analysis. Then, a mind map was developed where the five major dimensions related to Slow Fashion consumer behavior were identified: “ethical values”, “sustainable consumption”, “consumer motivations”, “consumer attitudes”, and “sustainability awareness”. We than related the mind map with the main conclusions of the literature review. The main limitation of this research results from the low number of published papers approaching the research concept. We were, however, able to identify the main concepts associated with the movement of Slow Fashion, thereby contributing to the available information on the variables that impact consumers’ purchasing decisions.
