Winter roars in like a you-know-what. (We meant lion, smart alecks.) This year, fight back swathed in shearling. We’re seeing the soft stuff lining and trimming coats designed by everyone from Giorgio Armani to Miuccia Prada to man-of-the-moment John Varvatos. Sheepish about dropping serious bucks on such a coat? Watch for the sheepskin look to graze right into the shops and catalogs of most of your favorite outerwear emporiums.
