Saks Fifth Avenue officially unveiled its holiday windows this week, with displays that include an abundance of nondenominational snowflakes, crystals, and stars. And the store got into the fashion spirit, with one-of-a-kind dresses by Carolina Herrera, Kaufman Franco, Michael Kors, Ralph Lauren, Zac Posen, Oscar de la Renta, Giambattista Valli, and more in the windows. And the super-chic windows brought out the stars — Tory Burch, who designed a crystal curtain, came with her sons, Zac Posen attended to promote his dress, and Marlo Thomas stopped by as well.
