You need a wind block. Otherwise you will freeze when winds are gusting and the temps are below freezing, no matter what you do I think.
If it is not windy, loose fitting and layers is best. No high tech is needed, just lots of layers. Wool is the best low tech, although even cotton in layers will work. And loose fitting ice-man type boots with a small toe warmer in each. And a hand warmer in each glove. On the head, if it is really cold you can have a hood from a sweat shirt, a knit hat, a hood from your coat, and also a neck warmer (I make them from a knit hat with the top cut off) over neck and face. Loose fitting gives you air layers, and air insulates.
