The origin of the phrase "the full monty" is said to have derived from the existence of a large British chain of men's clothing stores know as Montague Burton and Co. - Monty's. This is where the working man bought his best clothes. If he purchased a suit, shirt, tie etc. all at the same time, it was said of him that "he went the 'full monty'". This subsequently came to refer to any situation embarked on without restraint. The advent of the movie by the same name seems to have irrevocably changed its meaning to "complete nudity".
