This is a review of the exhibition El Arte de la Indumentaria y Moda en Mexico 1940–2015, which was the first survey of Mexican twentieth century fashion, on view at the Banamex-Palacio de Iturbide, Mexico City from May 4 to September 25, 2016. Examining the curators’ argument that the various cultures that have intermingled in Mexico have left a mark in its fashion and ethnic dress, this review explores the tension between tradition and modernity in the understanding of culture and dress in Mexico.
