No idea yet! I don't think I'll be cooking as much this year, which is usually my primary concern regarding the outfit. We'll be having two this year, one with my family and one with our friends. I usually dress up a bit more for all of the family outings; a loose sweater dress, tights, and heels usually works well. For our annual friends dinner, it's usually an oversized/fluid sweater with jeans and short boots.
(Rachy! Crab on Thanksgiving?? Sounds yummy to me, crab is my favorite! But hey if you need your turkey fix, it's too bad you don't live closer to me: We smoke ~30-40 lbs of turkey for Friendsgiving every year. I wonder where one would find Thanksgiving police.)
