This paper focuses on the relationship between fashion, language and the body. We refer to two theoretical starting points: Lotman's definition of language as a “primary modelling system”, and the relationship, identified by Barthes, between “real” and “written” fashion. The paper studies this relationship within four fields: the performative power of brands, the “playful” role of writing on T-shirts, the function of the written language in some examples of contemporary fashion, tattoos and permanent body modifications between writing and fashion practices.
