Abstract: This article focuses on the used underwear market, defined as the market for underwear that has been worn by one or more individuals and sold unwashed, meaning it contains deliberately left secretions and fluids. It distinguishes websites where the nature of the product sold must be concealed (such as resale websites for secondhand items) due to the prohibition of the transactions, and websites where the product can be openly discussed (such as websites specializing in the sale of sexual items). This distinction allows for the study of the issue of product qualification and disqualification in a contested market, which has been hardly explored. More broadly, this article helps identify the main characteristics of an overlooked market that, until now, has only been the subject of sensationalist analyses. 

"this is a "contested market," that is, a market in which some people would like to carry out transactions, but third parties oppose them on the basis of moral considerations. This opposition can then translate into constraints placed on the organization of the market (Roth, 2007), such as its prohibition (e.g., organs), the prohibition of advertising (cigarettes), difficulties in obtaining a bank loan (pornography), the imposition of punitive taxes (sodas), or even the stigmatization of participants in the transactions. Contested markets have been the subject of a substantial body of literature over the past decade (e.g., Steiner and Trespeuch, 2014; Bertrand et al ., 2020; Bertrand and Panitch, 2024; Gradoz and Dekker, 2025), and this article proposes to analyze the used underwear market based on this literature, moving beyond the sensationalism that has prevailed until now. This literature has focused in particular on the justifications used by third parties to challenge the existence of certain markets, or on the strategies implemented by participants in transactions to cope with the constraints resulting from this challenge."
