GREEN ACRES: America’s morose real estate market just got a vote of confidence from none other than Karl Lagerfeld, who has swept in and bought himself a six-bedroom, 1840 landmark building on an island in Lake Champlain, Vermont – sight unseen (although he’s got photographs). “I love it. It’s very much Emily Dickinson,” Lagerfeld said backstage at Chanel, describing a landscape not unlike the North of Europe, from which he hails. The designer is already plotting a décor worthy of a Vilhelm Hammershoi painting – and perfect for a fashion campaign. “I’ll start doing the Chanel campaigns there,” he said.
