How should a tennis necklace sit?

Generally, a tennis necklace should sit just above or below the neckline of whatever a person is wearing. For most people, tennis necklaces that are 16 to 18 inches long are ideal. However, some may wish to wear a longer piece if they are tall, have a wide neck or are wearing a low-cut top or dress. Explore a collection of tennis necklaces on 1stDibs.
