For those readers in cold climates who don't want to see one more starlet shivering in a mini, this look's for you. Sienna proves that it is possible to look chic in a warm coat: All you need is one that cinches at the waist with a fancy fur hood. Add one abstract-print hat, cozy-cute booties and the ultimate red bucket bag, and it's a look that will turn heads (as far as they can turn in a puffer, anyway).
