Bring more clothes than you think you need. Bring at least couple layers of long johns/thermal underwear, wool socks, warm shoes, couple layers of gloves, warm hat.. Overall you should have at least 3 layers especially if you're staying still. If you have extra you can always put on more (so always have extra) + you'll have blankets and hopefully a warm sleeping bag with you so you should be fine.
