The latest It bag for the 1 percent? Jil Sander’s “Vasari,” a “long rectangular silhouette” made from 100 percent coated paper. Translation: It’s a glorified lunch sack. And it could have been yours for $290 if it wasn’t already sold out. Sure, it may be a brown paper bag with stitched seams on each side, a couple of gold-colored metal eyelets, and “Jil Sander” stamped in barely perceptible type at its base, but it’s a brown paper bag nonetheless. If Sander’s brand of “Derelicte” wasn’t offensive enough, the designer also offers a black leather version for $630.
