Is an 18-inch necklace too short?

Whether an 18-inch necklace is too short depends on a few factors. If the necklace length causes it to hit right at the neckline of your top, you may want to go with a longer or shorter option. People with wide or short necks may also find necklaces longer than 18 inches more flattering. On 1stDibs, shop a variety of necklaces.
