How to easily measure the neck size
IMPORTANT: The measurement is for your neck, not the length of the jewelry item.
1. Take a piece of string, ribbon, yarn, or other flexible material. Wrap it around the neck at the height where the collar would normally rest – just below your Adam's apple.
Mark a point on the string where it overlaps.
2. Take a ruler, measuring tape, or other measuring device. Hold the string against a ruler to find the measurement.
