A princess length necklace measures 17-19 inches and falls just below the collarbone, resting at or above the neckline of most clothing.
This is the most popular and versatile necklace length for women, working well with crew necks, scoop necks, V-necks, and most casual to business attire. The princess length is long enough to be elegant but short enough to showcase a pendant or diamond solitaire effectively. It complements most face shapes and body types.
This length is the default choice for many pendant necklaces and is standard for graduated pearl necklaces. For most women, an 18-inch necklace hits the perfect spot just at the base of the neck.
