A guide to modern etiquette for socially unskilled American men presents wry and lighthearted guidance by a refined English writer and covers everything from dressing correctly to avoiding embarrassing faux pas. Original.
This book was published in 2006, and it's suitably modern. It doesn't stress rules, since most people expect you to be flexible anyway, but instead shows appropriate attitudes to have and/or things to say in a huge variety of situations. The One Great Rule of stylebooks is, in my experience, that being a gentleman consists of being considerate to the needs of others and that little else is necessary.
Henry Russell is very funny in his candid, realistic approach. He doesn't focus on the usual round of what cut of suit to wear and which fork to use, but instead presents a few paragraphs on each topic and sub-topic, including but not limited to what to say at a bar mitzvah, what to write in a thank-you note, and how to get rid of boring people who want to talk to you. It's not so much a plan of action as a guide to strategy.
