NATURE’S CALL: Rather than show a collection for spring — an undertaking he deemed “too expensive; there’s a lot of financial stuff” — Miguel Adrover, the creative director of German-based eco-minded clothing firm Hess Natur, has teamed up with Whole Foods to create a T-shirt to be sold exclusively at the retailer’s stores and on its Web site. The shirt, which will retail for $19.99, features an earth image, which Adrover said was inspired by his concerns for the environment. “First [you think about] what goes in your body, and then what’s on top of the body,” he said, adding he has not ruled out a line of eco-fashion for a store such as Whole Foods. The company plans to produce 10,000 shirts. Adrover, meanwhile, said he hoped to show a collection in February.
