                    Also called “Brooks Brothers model,” this is one of America’s leading styles. Sometimes called “university model” since so many of the devotees are college students or college graduates. Straight hanging. Shoulders are narrow and extremely natural, with either no pads or very little padding. Three or four buttons on the jacket; there are no two-button versions. Pants are slim and slightly tapered, commonly with no pleats. Cutting-edge, but the aim is intensely conservative—the very opposite of the equally popular “Hollywood model.” These two models form the two extreme poles of current American fashion. In America, the Ivy League model is urban, often described as “the clothes worn on Madison Avenue.”
