All the department stores had their window displays up and running in time for Black Friday last week. Barneys unveiled its Gaga’s Workshop with Mother Monster–themed windows, and Tiffany & Co. took inspiration from the carousel in Central Park. Saks Fifth Avenue brings the picture book Who Makes the Snow? to life, and Bergdorf Goodman’s intricate display is titled “Carnival of the Animals,” complete with paper aardvarks and leather monkeys. See all the images in our Holiday Windows Slide Show.
