A RUGGED COUNTRY LOOK that will be hitting city streets in a big way this fall is the parka. Make sure it has elasticized waist and a hood, especially a hood that is fur trimmed. From Ceresnie & Offen Furs, comes a Marvin Richards-brand green brushed nylon parka with fox collar. Wear the sporty parka with the simplest of bottoms, the best being skinny leggings and knee-high black leather boots by Joan and David, available at Roz & Sherm. Classic COVER
