How to measure
For the most reliable result, measure at the end of the day when your hands are at their largest. Keep the measuring tape or paper strip snug, but not tight.
Necklace size
Measure a necklace you already own from end to end, including the clasp, and compare the result with the chart.
Cuff size
Measure the circumference of your wrist or arm at the exact point where you want the cuff to sit.
