Winter has already passed, but you can always plan ahead for the next time it comes. That way, you don't need to panic that you don't have any Ski Clothing yet if you plan on going skiing. I've tried buying clothes less than a week before going skiing and let me tell you that it's not easy task.
Also, I think ski wear are probably on sale during this time of the year since it's off season. I'm just not sure which stores are selling them, though.
