This article offers a critical exploration of exclusionary practices enacted in Italy towards migrant prostitute women. It identifies the double construction of migrant prostitute women as victims of sex trafficking and as illegal/criminal migrants as a dominant paradigm that informs policy approaches aimed at addressing their presence in the country. It explores how this paradigm has emerged in the specific context of contemporary Italy, how it has been sustained, by whom and with what consequences. By drawing on the exploration of a specific incident, the article shows how gendered and racialised constructions of dangerous migrant sexualities can inform decisions over what determines the slippery and unstable demarcation between those who are identified as victims and those who are identified as criminals. Finally, the article suggests that, caught within the restrictive victim/criminal paradigm, migrant prostitutes fail to be recognised and treated as subjects.
