“Smart 35” collar insert

An employee with a stand-up collar used to signal his profession as a white-collar worker, distinguishing himself from the proletarians, the workers. Unlike their physical work, activities in offices were clean, which was reflected in suits and white stand-up collars. The term “Stehkragen-Proletarier”, which corresponds to “white collar worker” in English, has become vernacularised for these office workers.
