MAC’S BACK: MAC Cosmetics and Prabal Gurung are teaming for what they call an ultraluxe, deco-themed holiday collection. Price points for the 14-stockkeeping-unit, limited-edition offering will range from $20 to $70, a higher price point than MAC’s typical offerings. The lineup will be available in North American stores on Nov. 26 and will also be sold in select international markets in December.
