Perhaps it’s the current call for transparency in politics and business that is inspiring all the pellucid fabrics on the runways. These filmy layers are especially effective for see-through outerwear. Designers use clear plastic or chiffon (or plastic lined with chiffon), as well as coated organzas and parachute nylons for voluminous parkas or “shower cap” sneaker covers.  Plaid versions create pattern play with striped under-layers, and glistening paillettes add to the diaphanous feel.
