RALPH’S APRES-SKI: Polo Ralph Lauren is taking to the slopes over the holidays. On Monday, the label will host a cocktail party at its Gstaad, Switzerland, store, followed by a dinner for 50 guests at The Palace hotel there. And in the new year, the label will fete its new St. Moritz store on the Via Serlas, with a party at the boutique on Jan. 2. Tyler Brûlé, editor in chief and chairman of Monocle magazine, will host the party at the store, the design of which is based on the aesthetic of classic cars mixed with contemporary elements. The store’s decor features tumbled French limestone floors, white lacquer fittings and a teak ceiling. And appropriately for its Swiss location, the store will house the first stand-alone Ralph Lauren watch boutique, along with a full selection of Ralph Lauren Collection and Black Label ready-to-wear for women and Purple Label and Black Label for men.
