The Workshop is the in-store holiday shop at Barneys, and it was designed by Lady Gaga. It's 5,500 square feet of bright colors, crazy shapes and a gigantic cartoon statue of the superstar herself.
"It's a 'Charlie and the Chocolate Factory' moment," Gaga said. "We wanted it all to be whimsical and fun, with a sense of art and fashion."
There are hair bows attached to headbands, iPhone and iPad covers and stiletto-heel holiday stockings. Lady Gaga says she hopes the composition notebooks splashed with her logo will be given as gifts.
Stylist Nicola Formichetti served as art director for the Workshop. Gaga said he oversaw the day-to-day development of decor and products - each one exclusive.
"This was very personal and very emotional for us," said Formichetti, who also helps design Gaga's concert costumes and personal wardrobe.
There are studded leather motorcycle jackets for infants and Gaga-on-a-motorcycle ornaments - a wide spectrum of products aimed to appeal to many ages.
In the candy shop section, there are cookies shaped like little monsters (Gaga's affectionate term for her fans) and rock candy necklaces. Inside the boudoir, sort of a tent shaped like a wig, there are hair bows and hologram-effect nail polishes.
Twenty-five percent of each product bought from the Workshop or online will be donated to Gaga's anti-bullying Born This Way Foundation.
Gaga's Workshop is open through Jan. 2.
