Museo Nacional de la Historia del Traje, National museum of costume history in Monserrat, Buenos Aires, Argentina

The National Museum of Costume History collects garments, textiles, and accessories that document the evolution of Argentine fashion across different periods. The collection spans from colonial times to the 20th century, showing how clothing changed over time.

The museum was created in 1972 on the initiative of the national Ministry of Education and Culture and Julio César Gancedo, director of the Museo Histórico Nacional, and opened on 11 November of that year. It was housed in an 1830 Italianate "casa chorizo" donated by Nydia Luzuriaga de Mercau. Its creation followed a 1969 costume exhibition at the Museo Histórico Nacional. The building was declared a National Historic Monument in 1990.

The exhibition rooms display traditional clothing from different Argentine regions, showing how dress styles varied by geography and social class. You can see how people in the countryside dressed differently from those in cities.

The museum closed permanently on 28 February 2026 under decree 862/2024, so it can no longer be visited; its roughly 9,000 pieces, most of them National Heritage, were transferred and staff reassigned to the Museo Histórico Nacional. The 1830 Italianate casa chorizo that housed it, declared a National Historic Monument in 1990, was announced for reuse as a space for emerging artists.

The collection includes carefully documented information about manufacturing methods and materials used in Argentine clothing production from different eras. These details let visitors see not just the finished pieces but also understand how craftsmanship and local fabrics were valued in each period.
