There are two schools in classical men's tailoring: the British one, which is best embodied by Savile Row, and the Neapolitan school. If English clothes owe their DNA to an equestrian past, Neapolitan clothes owe more to courtiers of the King of Naples. To this day, the Italian competitors to Savile Row produce suits that have an insouciance better suited to a boulevardier than a banker.
Some trademarks of Neapolitan tailoring that are still with us today can be seen on an Attolini suit, including the trumpet sleeve - it narrows at mid-arm and opens like a trumpet's mouth at the cuff to produce a sleek silhouette - and the baerchetta ("little boat") breast pocket, whose curvature mimics the line of the chest. Also note how the lapel is ironed to gently fold over and hide the suit's top button.
