This time of year, I am all about being comfortable and cozy.  Which is why I am digging drapey tops, capes and ponchos.  To keep it classy, make sure your bottoms are fitted.
I also go from wearing blacks and greys to whites and nudes.  If you are on the west coast, you can probably get away with a leggy look like the one above, but either way just grab similar colors to create the same feel.
The first week of December I wore red nails to celebrate the start of the season then I did dark green but this week I am feeling the glitter.  I think I will do either a white or pale peachy color with a little accent nail or a little bit of Essie's Beyond Cozy on each nail.
