Classic fit jackets are wider at the waist and longer in the tail. Pants are fuller in the leg, with a standard height waist.
You've got to hand it to the Italians; they know their warps from their wefts, their worsteds from their woolens; they know how to make a cracking suit. Paying homage to centuries of stellar tailoring, these suits were woven in some of Italy's finest mills. A touch of Italian class and a sprinkling of Jermyn Street elegance. Magnifico.
