I have one word for this week: Brrrrrrr. (Well, I have a few others but I'll keep things clean around here).
Dressing for 10 degree weather is all about layering your clothing. I'll throw one of my faux fur vests under a jacket and over just about anything. If you don't have one, I'd highly suggest you buy one..It's the perfect time to shop because of all the insane sales going on!
