Wondering what to wear to St. Moritz?

Coming out of Fashion Week (in New York), this from designer Oscar de la Renta: He trimmed his chunky knit sweaters with fur. Fashionistas are saying we should expect to see those sweaters, worn with black satin tights and furry flat-heeled boots in the apres-ski lounges in St. Moritz at Christmastime. But satin tights at Wolf Creek or Monarch? Only if there's a way to add a little Gore-Tex.
