Guests can make a cameo at this fete like one of the privileged few who would have been invited to Truman Capote's masked Black & White Ball in honor of Katherine Graham. A black and white combination is timeless and easy to find -- it's a hit this spring. Try a black jacket over a white dress or this black chiffon shift with a silver satin bow from Chloe. You don't have to travel to Bergdorf Goodman to find a Truman-esque big scarf. A neutral-color wool throw in the living room strategically placed over the shoulders could fill the bill. Complete the look with a pair of tortoise-shell square-shaped eyeglasses. Host/hostess note: Keep a supply of gin, vodka and other essential martini ingredients and glasses always at the ready.
