First, understand that no one clothing combination is going to work for all situations. I go running at -30°C in only a light, highly breathable shell and thin baselayer with very thin gloves. I would sustain severe frostbite in minutes if I were to wear the same clothes while ice climbing.
The biggest error I see is that people don't vary their clothing to match their heat output. It's not about ‘layering’ but about finding a ‘moving’ outfit that's minimal and a ‘sitting’ outfit that's very warm.
Dress for where you will be in five to 20 minutes rather than where you are. When you first step out of the car and into the cold to go for a ski tour or winter hike the temptation is to dress very warmly. But do that and you'll soon sweat and get your baselayer soaked, the insides of those big gloves wet, and then you're going to be cold. Better to start a little cold.
