Whether it’s a ball gown or a little cocktail number, a black dress is synonymous with chic, sophisticated style. And one that boasts beautiful yet simple design elements, like a V neckline, a fitted waist, and a floaty skirt, will come out of the closet time and time again. The right accessory, whether it’s a string of pearls or patent-leather flats, will make the dress appropriate for black tie or something slightly less formal.
