Res Materia is an artistic research project by fashion designer Sanne Karssenberg that proposes a personalized form of the reproduction of garments and an alternative form of value creation. The title Res Materia is inspired by the Latin phrase Res Publica, meaning ‘public affairs’ or ‘commonwealth’. Res is a Latin noun for a substance or a concrete thing. ‘Materia’ is Latin for material. In this project, the material and the thing, or in this case, the textile and the garment, are the starting point for an embodied reproduction of garments—an attempt to bring change into ‘public affairs’.
