Valued as a $28 billion industry in 2021, the second-hand clothing industry, or thrifting industry, has been exploding (2020 Fashion Resale Market and Trend Report, 2020). This has been aided by a myriad of technological advancements, social movements, and economic factors. The goal of this thesis is to uncover consumer behaviors leading to this growth across behavioral, emotional, perceptual, and belief factors. Additionally, this thesis aims to provide strategic implications for marketing professionals, create recommendations for brands to successfully enter this industry and target consumers. In this study, a Qualtrics survey was distributed to students at Arizona State University. The results were analyzed through Microsoft Excel. The results showed that in order to be successful in this industry, brands should: emphasize sustainability in marketing, increase brand awareness, highlight feelings of pride in products, uniqueness, and affordability, mitigate feelings of poverty, low quality, and lack of variety, understand the perceptual differences in shopping versus thrifting, and take advantage of branded fashion.
