There are all kinds of men's fashion articles out there - such as which sportcoat or blazer to own if you're only gonna buy one, the most versatile shirts to own, and ten classic pairs of boots for any season. But, those are all based about specific items of clothing, or shopping advice on how to look sharp. Which are great, but what about some more basic knowledge about how to avoid looking goofy, or how to wear what you already own to its fullest?
The excellent men's wear blog Put This On address those very questions in their great article, Twenty-Five Pieces of Basic Sartorial Knowledge So You Don’t Look Dumb, in which they recommend such rules as "Unbutton the bottom button of your jacket. It’s not intended to be buttoned," to "Your tie knot should have a dimple," and "20. Never wear visible socks with shorts... 21. Or any socks with sandals."
