What necklaces make the neck look longer?

Generally, longer necklaces make the neck look longer. The reason for this is that the necklace pulls the eye from the neck downward, creating the illusion of added length. To visually elongate your neck, choose matinee-length necklaces, which are 20 to 25 inches long, and opera-length options, which are 26 to 36 inches long.
