Simple, durable and sufficiently stylish, good from -10 down to -40 Celsius if I'm moving:

• wool coat, long so you don't necessarily need long underpants
• thick wool sweater with buttons, t-shirt or shirt with collar underneath
• loose leather mittens with wool lining, fingerless gloves underneath
• wool cap that reaches the bottom of your ear lobes, wool scarf
• slightly thicker jeans than usual, no long underpants needed with long coat
• thick leather boots with plenty of room for your toes, wool socks on top of normal socks if really cold
