Style Rule # 3 - Jacket Buttoning Etiquette

I notice this fashion fopa a lot among men both fashionable and fashion less; not knowing which button to fasten when wearing a dress jacket is a common shortcoming. The proper button(s) to fasten depends on the number of buttons you have on the jacket. If you are wearing a two button jacket you should only fasten the top button thus leaving the bottom button undone. If you are wearing a three button jacket, you should only fasten the middle or second button, leaving the top and bottom buttons unfastened. When wearing the rare single-button-jacket, you should only fasten the obvious one button. Finally, when wearing a double-breasted jacket, you only need fasten the top and second buttons, the three or bottom button should remain unclosed
