Abstract: We learn a great deal about others from what they wear. Outfit choices can signal profession, social class, culture, lifestyle, gender, sexuality, and aesthetic taste. How is such sartorial communication possible? Marilynn Johnson (2022) suggests that clothing can be understood through H. P. Grice’s intention-based account of non-natural meaning. While this proposal shows that clothing can convey communicative intentions, it leaves open crucial questions about how clothes can systematically acquire information potential, and when that information is successfully communicated. I address these questions by developing a framework for sartorial communication, drawing on Robert Stalnaker’s account of context and common ground. Unlike speech, wearing clothes is continuous, and its audience keeps shifting. This raises distinctive problems: What constitutes the context of utterance? Who counts as the intended audience? And what determines the common ground that is required for communication to succeed? I argue, first, that communities generate sartorial conventions through repeated, meaning-conveying use, thereby enabling clothes to acquire non-natural meaning. Second, knowledge of these conventions is required for a shared common ground. Third, since not everyone knows the relevant conventions, sartorial communication is conditional: it succeeds only in contexts where a member of the intended kind of audience is present.
