Barneys has teamed up with Elle magazine and eBay to promote green retailing, and Project Blue is the name given to the special denim recycling project that has resulted in eight one-of-a-kind couture denim designs by Versace, Stella McCartney, Derek Lam, Alexander Wang, Bottega Veneta, Rodarte, Rogan and Ann Demeuelemeester. All designs, created from a collection of donated denim Barneys had been assembling since the previous summer, are currently on display in the retailer’s flagship store windows in Manhattan, but more importantly can also be seen and purchased on the Internet. As of 7 pm last night, the eight designs went on the auction block at eBay. Bidding began at 99 cents and continues through May 10. All proceeds will eventually benefit Oceana, the global organization focused on ocean conservation.
