The best part about the right outerwear is how it has the ability to pull an entire outfit together, or to make the outfit, really. Because of this, and because of the fact that I've spent most of my life in Wisconsin and Minnesota, I've invested heavily in outerwear. This particular coat I bought at J. Crew years ago, and have continued to love every winter since. Double-breasted pieces have always been a favorite of mine, and the camel color made this coat far too pretty to pass up. I was living in Minneapolis at the time, and had reservations about the shortened sleeve length, but between long-sleeved layers and super warm mittens, it has never been a problem.
And even after all these years, it still makes an oversized hoodie-tunic thing and leggings into an outfit.
