Should I get an 18-inch or 20-inch necklace?

Whether you should get an 18-inch or 20-inch necklace depends largely on where you want the piece to fall. An 18-inch, or princess-length, necklace usually hits just below the collarbone and can work well for displaying pendants. A 20-inch, or matinee-length, necklace will rest a little further below the collarbone and can be ideal for creating layered looks with other necklaces. On 1stDibs, shop a wide variety of necklaces.
