Measuring Your Wrist Size

1. Measure your wrist with a flexible tape measure (or a strip of paper) just below the wrist bone, where you normally wear a bracelet.
2. If using paper, mark where it overlaps, then measure that length with a ruler. This is your wrist size.
3. Refer to the bracelet chart below to choose your bracelet size and desired fit.

Standard Necklace Lengths

Knowing your neck measurement helps you pick a comfortable, flattering length:

• Choker: 16" / 40 cm.
• Princess: 18" / 45 cm — usually sits just above the collarbone.
• Matinee: 20" / 50 cm — typically rests below the collarbone.

How to Measure Your Neck

1. Wrap a soft tape measure around your neck, keeping it parallel to the floor.
2. Add 2–4" (5–10 cm) to your neck measurement to get your minimum recommended chain length for everyday comfort.
3. For a true choker fit, you can use your exact neck measurement (or add up to 1"/2–3 cm if you prefer a looser choker).
4. If a length isn’t customizable, choose the next size up from your neck size. For example, if your neck is 17" (43 cm), pick a 20" chain rather than 18".
