The article focuses on the museum as a place whereas knowledge is produced and discusses the role of objects in the establishing of new field of knowledge. The starting point is the work on fashionable dress at Museum of Decorative Arts and Design in Oslo (Kunstindustrimuseet i Oslo) and the parade of dress exhibited there in November 1933. Fashionable dress were obtained from museums and private people across the country, documented and presented to the public as a living exhibition, with dance, parades and tableaux. With new studies of materiality as an inspiration, I explore the role clothing had in the museum’s effort to establish fashion and dress history as a new field of knowledge. I examine museological practices with clothing. I am especially concerned of these practices tendency to freeze precise meanings and relationships to clothing such that they could contribute to the larger work of creating history. I show how the museum established fashionable dress as so-called «museological facts» and I argue that the relations between clothes and body were central in that work. The museum was concerned to find the right bodies to display, disport and exhibit dress in ways which appealed to their contemporary visitors. At the same time, these bodies were to contribute to establishing dress as objects of knowledge within Decorative Arts and Design, with a specific social connection and correct esthetic expression.
