Growing up in the Pacific Northwest, I like to think that I've fairly well mastered the art of layering... because one second it could be pouring down rain, while five minutes later the sun has somehow come out and you are actually sweating. Classic Washington move. That being said, these are some of my favorite layering pieces for this winter. Whether you need something thick or thin to add to your ensemble, I've got you covered here. What's your favorite piece?
