As a textile buyer, Roosmarie discovered her passion for establishing fair production and supply chains. At the age of 28, she started her own company, Promax Corporate Fashion. Ten years later, she sold her company and worked as a CSR textile consultant for Amnesty International, Fair Wear Foundation, and Fairtrade. In 2007, she lauched her platform Clean&Unique. With her extensive knowledge of the (sustainable) fashion industry, Roosmarie now contributes to the Reflowproject for the Municipality of Amsterdam in the Netherlands.
