My favorite body warming accessory during the cold months is thick, warm, blanket-resembling scarves. I just love wool and wool-blend scarves. When the weather gets extra cold, I grab a thick scarf to keep my neck warm. But most importantly, scarves go with every outfit and all body types.
A nice wool scarf and a soft, comfy cute legging set is just what you need when the temperature drops below freezing. See below a little something I styled up from http://www.thegarmenthive.com .
