Collecting in museums today raises a plethora of issues when it comes to sustainability. For example, fashion collections require a considerable amount of time, space and resources to maintain the condition of the garments. Fashion collections often focus on craft and socio-historical representation as opposed to interrogating the wider implications that fashion and clothing have on the environment. The Fashion for Good Museum (2017-2024) in Amsterdam adopted the latter focus, particularly considering innovations and the impact of the fashion industry on people and the planet. Operating from a position of sustainability as well as being a young institution, the museum was uniquely positioned to reconsider what it means to collect fashion, employing a more democratic approach to ownership, with shared responsibility among multiple stakeholders. The following article explores the Museum’s collection practices, reflecting on methods that could contribute to a more efficient, equal and environmentally sustainable approach to museum fashion collection management.
