From the designer William B. (a high-end designer who uses mostly Italian goods, and I think also produces for other high-end lines), this is a fantastic heavier weight denim twill, with cotton and rayon, has a certain crispness but is still very malleable, not at all stiff, definitely more of a cooler weather weight. The color is a mix of blue and gray twill, more gray on the reverse side. Make fitted skirts, jeans, jackets. Hand or machine wash in cold water, hang to dry.
