A scarf is key to keep out the cold! Scarfs should overlap sweater collar and should be tied as follows. place the scarf around the back of your neck overlapping your sweater collar, hanging down your front side. Hold the left side of the scarf in the middle of your neck so it drapes down your front like a neck tie, then take the right end and toss over your left shoulder, down your back while assuring that there are no twists.
