I wore this Ann Taylor sweater dress:

I thought the metallic blocking at hem and forearms made it festive but also can still just wear for every day too. It was very comfortable and allowed for lots of full belly. I'm going to wear to all our holiday festivities this year. We were at my brother's and I could have changed into sweats later but I didn't; the dress was just as warm and comfortable to lay about in, food coma style, digesting.
To travel down and back I wore boyfriend jeans because they are so roomy and comfy. With booties, sweater, pleather jacket, big scarf.
