How it wears

Find the length that flatters you.

Necklaces sit differently at every length. A shorter chain pools at the collarbone and frames the face; a longer chain drapes lower and reads as a soft column of light.

  • 16"Choker · sits high at the base of the neck.
  • 17"Princess · rests on the collarbone — our most worn length.
  • 18"Classic · falls just below the collarbone.
  • 20"Matinee · sits a couple of inches above the bust.
  • 22"Opera · a longer drape, beautiful over knitwear.
  • 24"Statement · a deliberate, elongated line.

Not sure? 18" is our most-worn length and flatters most necklines.
