Necklace length guide

Every chain has a 2 cm extender ring, so you can wear it a little shorter.

Necklace lengths
Length Where it sits Good for
16" At the base of the neck, on the collarbone Pendants, collars, the first layer
18" Just below the collarbone Everyday chains, the most popular length
20" A little above the neckline of a crew-neck top Layering under a shorter chain

Layering? Leave about 5 cm (2") between chains so each one shows.
