Why do men, why do male artists in representational function dress in the well-cut suit, today as well as 200 years ago? Why do even female artists choose to wear the men-suit? In examining a selection of self-portraits of the 19th and 20th century, this study deals with the development of the very symbolic ensemble jacket, trousers and dress-shirt. But not the changes in the cut of suits are particularly investigated, but events in terms of social policy, which supported the upcoming of the suit in his present form. Beginning at the French Revolution, this study surveys the male and female suit-wearing artist up to present time. The numerous examined paintings provide evidence for the extensive uniforming of the western male attire.
