Wear layers, but nothing cotton. Outer layer and gloves should be wind and waterproof. Socks should be well fitted and only one pair should be worn at a time.

For non diehard skiers, I always recommend going in spring when the weather is better and the days are longer. This being an El Nino year most likely means a long ski season as well as epic snowfall conditions. With the storms this week, it's snowing at a rate of about two feet per 24 hour period here in California, with the rockies getting about a foot a day. Not much fun in those conditions unless you're prepared for it.
