Necklace Length Guide

Where a chain sits depends on its length and on your height and build. Use this as a guide, then try lengths on in person to be sure.

Every length starts at the neck — longer chains simply hang lower.

Length Style Where It Sits
14" Collar Snug around the neck
16" Choker Base of the neck
18" Princess Just below the collarbone
20" Matinee Top of the bust
24" Opera Below the bust
30–36" Rope Long, or doubled up

Bracelet Sizing Guide

Wrap a soft tape measure or a strip of paper snugly around your wrist, just above the wrist bone, then match your measurement below.

Wrist Measurement Bracelet Size Fit
5.5–6" Small Snug on petite wrists
6–6.5" Medium Comfortable on most wrists
6.5–7" Large Relaxed, or larger wrists
7–7.5" Extra Large Oversized or layered look

Tip: add about ¼–½" to your wrist measurement for a comfortable fit — a little more for bangles and cuffs.
