The world's fascination with Italian style can arguably be traced back to Brioni. In the mid-20th century, Brioni became a "tailor for the stars," dressing men such as Gary Cooper and Clark Gable both on and off the silver screen. Consequently, Americans (and later the rest of the world) fell in love the streamlined Roman suit—that broad shouldered, V-shaped silhouette that was simplified by having the cuffs, pleats, and pocket flaps taken out. Brioni made other important innovations, such as hosting the first menswear fashion show, which took place in Florence, Italy in 1957. But it's really their role in popularizing Italian style around the world that cements their position as one of menswear's greatest.
