The full-time traveler was on Charlotte Ronson's mind for Fall, but not the business-class type. Hers was a peripatetic seventies gypsy, too busy seeing the world to get caught up in the Studio 54 thing. The overall mood was of fluid, thrown-together sexiness. Vagabond wear included long pleated skirts in raspberry, rust, and floral prints; they looked great with belted tunics and hammered-silk tanks. An army green utility cape and a gray cocoon jacket added a dose of functionalism, while a sheer black lace blouse was pure form. We could have done without the shiny harem pants that joined the caravan, but—playful turbans and all—it was an eclectic mix that worked.
