[1] In 1990 Grose co-founded Esprit's e-collection division, a five-year research and development project marketed in 13 countries, which is cited "as the first ecologically responsible clothing line developed by a major corporation" and in doing so, Grose "set pioneering standards for the textile industry".
Grose's project began by researching the environmental impact of making Esprit clothing - from growing fibers, to dyeing, manufacturing and garment finishing.
Grose also began contracting with crafts cooperatives to hand-knit sweaters and make buttons and jewelry from tagua nuts.
Grose believed that community development and fair treatment of textile workers was as important a part of the project as using more sustainable materials.
