To generalize a little: the Italian way is no break at all; the cuffs may not even quite reach the top of the shoe. Â The American way is a generous break; the cuffs are 1/2" longer than they need to be to reach the shoe.
Strange, because we always thought that Americans have too short trousers (JFK look). The Italian rule every tailor here will use -if not asked differently-, as I know, is: "you have not to see socks while walking (not just standing)". So trousers will rest on the shoe with a generouse break. And trousers are always cuffed AND slanted (the rear is longer and it is 1-2 cm above heel of the shoe). My, personal, rule is: trousers have no break, but touch the shoe; very hard to meet perfectly.
