This Master's Thesis is made up of a predominantly descriptive part, while the practical part refers to conversations with fashion designers and museum curators, which are listed in the chapters that lead us to the elaboration and conclusion of the topic. The work is conceived through five chapters in which the process of development of musealization of fashion is presented, as well as the role and function of museums in cultural society with adjustments in relation to fashion and contemporary art. Some of the authors to be referenced in the museum-focused work will be Andre Gob and Noemie Drouguet and the work 'Museology' (2007), and the key literature from which this work is based is 'Encyclopedia of Clothing and Fashion', by Valerie Steele (2005). The ‘Fashion museums and collections’ chapter will provide insight into the process of developing the musealisation of fashion from the first private fashion collections of collectors, through the display of historical clothing in the museum space to the commercialization of fashion exhibitions through the work of Diane Vreeland. The aim of this paper is to show the role of the museum as a space for the promotion and presentation of fashion works and trends and to prove that despite the many curators who do not approve of cooperation between museums and fashion houses, fashion deserves its place in the museum and is as valuable an art branch as all others artistic areas.
