Abstract
Fifteenth-century Italian urban and ecclesiastical authorities sought to regulate the laity's conspicuous consumption of dress, sometimes resulting in canon law petitions for exemption on the grounds of custom. By exploiting an ambivalent definition of custom according to status, wealthy men and especially women successfully sidestepped regulation. Critics of luxury such as the Franciscan Observants, who encountered similar arguments in confession, countered this permissive understanding of custom with alternate criteria for determining proper dress tied to the morality of the economic behavior that made luxurious dress possible. Overlapping definitions of custom drawn from canon law and moral theology thus provided both fashionable people and their confessors a way to negotiate and contest their status.
