There are really two things I consider when purchasing ski apparel. The first is whether it will keep me warm and safe during the coldest and most extreme skiing conditions. The more durable and weather resistant the fabric, the more likely your ski apparel will give you many years of comfortable skiing.
The second thing I consider is whether the style of my prospective ski apparel is whether the apparel is timeless. I only ski a few times a season, and I want to know that I will feel confident pulling out my ski pants and jacket season after season and knowing that I will be able to look stylish and fashionable. This usually means primary or basic colors and no flashy detailing. It also means buying what looks good on me, not what the fashion magazine say is the hottest ski apparel at the moment.
As long as you consider these two criteria, you should have no problem wearing your ski apparel year after year.
