Winter boosters. Those are the things worth adding to your wardrobe right now to boost both style and warmth. The turtleneck sweater is the focal point of a number of top designer collections this season, and a version in cashmere feels good and looks terrific. The Herme's scarf, real or fake, is a way to brighten a favorite old outfit, or tie it on the shoulder strap of your handbag, Babe Paley fashion.

A man's reversible muffler works for both daytime and evening, depending on which side you feature. And kids' cotton ski undies are great cold-weather liners for play or for sleeping.

The perfect shoe to wear for the holiday season, and far beyond, is the black flat. The version we've shown is in black damask, but satin or tapestry would do just fine.
