Spicy Cinnamon Champagne is the awesome name of the equally awesome orange waffle-knit thermal that I purchased at J. Crew. It is, naturally, a final sale purchase but I never seem to mind the no-return policy given the great price.
I found that this shirt runs small, at least for my liking, and I purchased it in an XL. Certainly I could fit the smaller sizes but I like my tops roomy and a bit on the long side as to pair with skinny jeans and such.
