The world is wrapped around Lady Gaga's fingers… well, at least 5,500 square feet at Barneys NY in Manhattan is. The fifth floor of the Madison Avenue flagship is now Gaga's Workshop. Aside from its stellar decor and design – under the guidance of the Lady's friend and creative director Nicola Formichetti – the pop-up offers her little monsters a unique holiday shopping experience. There's a $95 metallic gold cookie in the shape of her famed Alexander McQueen armadillo shoes, $225 press-on nails decorated with NYC monuments and a $395 Gaga bust candle that weeps wax. Worried about price? Twenty-five percent of all proceeds will benefit Gaga's Born This Way Foundation, aimed a youth empowerment. Fans can visit Gagasworkshop.com for a trippy preview to the shop, buy limited-edition Gaga goods and unlock codes for prizes.
