Get the the full monty mug.
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.

Doesn't necessarily mean to take off all your clothes. It just means the "whole thing" or going the "whole way" not stopping at a point.

Get the full monty mug.
British slang phrase meaning "everything, the whole lot" or, when used as an adjective, "all the way".
My girlfriend left me, she said it’s because I was not willing to go the full Monty.

1. totally naked for the benefit of another person, as in the 1997 movie "The Full Monty"
2. full erection
taken from the movies' description- The women cheer them on to go for "the full monty" - total nudity. She was totally surprised when she returned to find him standing in the doorway with no clothes on and a Full Monty.

Trad. Slang: Brit. Royal Navy,

A Full Monty is the act of requiring anyone onboard ship who grows a beard or moustache to grow the opposite partner or shave it all off.

If you have a beard, you must grow a moustache to go with it; the opposite applies - if you have a moustache, you must grow a beard.

The act of having the Beard and Moustache together is known as "having the Full Monty".
Crewman 1: "Look at the Face lace on that bloke!"
