You may have seen photos of some of the incredible art on display inside Gaga’s Workshop at Barneys this holiday, but have you looked at the extravagant merchandise inside? The Workshop is filled with toys, clothes, accessories, candy and other tokens that any Gaga-obsessed teen (or adult) is sure to beg for this holiday. Items are on sale through January 2 and feature price points from $8 (for a Bic pen) to $2000 (for insane Gaga-inspired boots). There’s even a Gaga onesie for the tiniest fan born that way. 25% of the proceeds go to charity.
