British high street taylors Montague Burton, now called simply Burtons, did a range of cheaper suits, with optional waistcoat. I think this was around the 1940's. Having a Full Monty was going in and getting trousers, jacket AND waistcoat, especially if you were a soldier going back to civilian life.
I've got the Full Monty organized for my wedding.
