1. Grab a piece of string. If you're measuring for a necklace with a pendant or charm, you can hang something with a little weight (like a small key) on the string to help it fall naturally into a V-shape.
2. Wrap it around your neck, letting it hang at the length you want the necklace to sit.
3. Mark the spot where the ends of the string meet.
4. Lay the string flat and measure it with a ruler or tape measure. This will give you your necklace length.

Stacking necklaces_ If you plan to layer your necklace with another one, choosing a different chain style than what you already have adds variety and keeps the layers visually interesting. And obviously the chain lengths would have to be different so they can stack nicely above each other. :)

Match or contrast with the charm_ Decide if you'd like the chain to enhance or offset the charm. The gourmet chain provides a calm backdrop, while the figaro’s pattern creates a bold, complementary contrast.

Personal style_ For a minimalist look, the gourmet or cable chains offer understated elegance. If you prefer a touch of character, the figaro’s vintage pattern adds a unique, expressive touch.

Also consider what type of tops you normally wear. Do you wear v-necks or usually a crew neck?
