Layering is a tricky game that is worth figuring out.

Smart layering is something that I'm still learning and working on every day as the degrees keep getting lower and lower. It's easy to go overboard and end up looking like a donut. Some days, though, I don't care how I look, as long as I get from point A to point B in one piece without limbs frozen off. 
For me, I've found that big knits (even though they are massive) and some lighter, but still warm underneath layers are what works the best. The trick is to keep testing and when you've found what looks the best - stock up but in different colours, textures. At least that's my idea how to go about this.
