Layer it on, as little or as much as you want with this season’s must-have jackets, coats, sweaters and more. This season, we’ve upped the ante on statement jackets. Beautiful embellishments transform a cool garment-washed plaid jacket. Take your pick of double-faced wool coats — angular stitches lend drama to a refined pale green coat, a hint of jester red delivers a bold pop to an easy open black coat, and a belted duo-shade gray robe coat will become a perennial winter wardrobe staple. Dynamic sweaters are the perfect complement to a crisp white shirt or a fluid silk blouse, yet thin enough to be layered under the season’s coziest cardigans.
