A worried reader asks etiquette expert Peggy Post of Good Housekeeping magazine whether as a woman she is required to take off her baseball cap for the playing of the national anthem at ballgames. This is a complex question.
"Although a woman may leave her hat on indoors or during the playing of the national anthem," writes Post, "a baseball cap is a different story because it's considered unisex. So, when wearing a cap, a woman should follow the same guidelines as a man does."
