OVERIJSE, Belgium - Dior, Lagerfeld and Versace eat your heart out. A Belgian horticulturalist has come up with the ultimate ecological fashion statement to give your loved one this Christmas: a skirt made of live grass. The clothes — skirts, tops and dresses — are the idea of Luc Mertes, who lives in the Belgian town of Overijse. The grass is grown on jute matting, instead of earth, for about 25 days, and is then made into garments which continue to grow while you wear them. The end product is striking, if not comfortable: the clothes weigh several kilograms (pounds) and the water needed to keep the grass alive makes them quite damp. "It‘s a bit of a joke, really," said Mertes, who tells the friends for whom he makes the clothes: "Make sure you water your skirt."
