I am not fashion conscious. I can honestly say that I've never spent a cent on Vogue, Allure, Cosmopolitan, or any fashion magazine, for that matter. If you ask me the brand name of the blouse or slacks I'm wearing, I would have no idea.
Of the over one hundred etiquette subjects I have taught, dress and etiquette are always in the top ten. Dressing is not like setting the table, where rules rule. Are there rules for dress? You bet, but there's a lot more freedom of style.
