Change hats, and I can go wearing the same thing I do on a daily basis. Good thermal underwear cotton, wool or synthetic. Boots large enough for heavy socks, or two pair. Two pair of gloves, one to keep your hands warm, and one thinner pair to wear while you shoot. Wool or heavy cotton shirt. Tie your wild rag over your head like a scarf to keep your ears warm, it can be worn under your hat. I wear a Carhart chore coat every day. They aren't the warmest thing going, but they are pretty tough and easily washable. Any tight weave pants that'll block the wind and you can stay warm to the teens with no problem.
