Abstract: There is disclosed a garment including a seat section and a pair of legs depending from the seat section in the form of trousers, and, optionally, a jacket extending up from the trousers to form a combination. The trousers have a front panel and a rear panel and the invention resides in the improvement wherein the rear panel is formed with a pair of vertical folds spaced laterally from one another with respect to the center of the panel, and wherein each fold runs down from waist level to a level at about mid-length of one of the legs so as to allow the seat portion to stretch laterally when a wearer of the garment bends down or stretches his legs laterally.
