When a man wearing a cloth jacket or a suit, both in a formal occasion, a ceremony, a dinner but also to work, the iron rule that etiquette requires you to never togiersi the jacket, not even at the table, especially if you are in the presence of a lady.
The story explains why, since the Middle Ages the shirt was condsiderata an undergarment to wear hidden under something else (vest, blouse, jacket), the most modern explanation lies in the fact that any shirt after little that was brought under a dress or jacket is still creased and it is not a pretty sight, it gives the feeling of tired looking, although it is perfectly ironed out from our wardrobe, then why risk it?
