Q: I have a black-tie event coming up—what do I do about a coat? (P.S. I don't wear fur.)

A: Fur gets a lot of people's dander up—there are more humane ways to stay warm on a winter night. Besides, unless you're expecting a gang of paparazzi to greet your arrival, you don't have to get fancy with a special-occasion coat (why invest in something you'll use only a few times a year at most?). In warmer climates, keep it simple with a trenchcoat, preferably in always-dressy black in an evening-friendly fabric: taffeta, satin, organza, or a synthetic with shine. Another happy strategy is to mix sporty with formal, throwing a well-cut wool coat or longer down parka over your gown. It's a modern, unfussy approach. And no animals will be harmed in the making of your outfit.
