I finally found a steady supplier of "RPL", so that I can continue to have various colors in stock! RPL is a rayon/polyester/lycra blend stretch woven gabardine that is a wonderful, easy-care, pants fabric. These are medium weight, so they will work for any season! The color of this one is a slightly heathery charcoal (18-0306). Just a bit of stretch in the width only, with wonderful drape. Perfect for tailored or drapey styles, slacks, skirt, jacket, suit. Easy care (but always test first!)..check Shannon's guide for RPL.
