This article theorizes the commodification of the recent resurgence of feminist activism through the concept of "feminist commodity activism." The focus is on the mass popularization of feminist-themed commodities, with T-shirts as a particular focus. First, I discuss how the mass marketing of feminist goods ties in with: (a) commodity feminism, by refetishizing commodities and consumption as empowering for women; (b) neoliberal feminism, through the construction of the feminist as an economic and choice-making subject; and (c) commodity activism, by entangling feminism with the discourses and practices of ethical consumption. Building on these concepts, I propose "feminist commodity activism" as a way to capture and further analyze the current commodification of feminism activism occurring at their intersection. I argue that feminist commodity activism instigates three further shifts: the commodification of the aesthetic experience of feminist street protest; the transfer of feminist activist agency to companies, charities, and entrepreneurs; and the branding of the feminist as a subject of value. Finally, the article considers the challenges that these shifts pose for feminist critique and politics.
