There are a lot of ways to categorize the rules of etiquette: business, dinner, conversational, and so on. One of my favorite old etiquette books included another, most clever method: by your anatomy. In Esquire Etiquette, which was published in 1954 in Great Britain, there’s a section that breaks down a man’s essential manners by body part. It’s a little long, but a cheeky and very enjoyable read. And while some of the advice is quite old fashioned (not many men today wear a hat they can alternately tip and lift), much of it still remains relevant for those who aspire to be old school gentlemen.
