If you're unsure which length to order, here's a simple method to help you find the perfect length:
Use a String: Take a piece of string or a thin strip of paper and wrap it around your neck, holding it at the spot where you want the necklace to sit.
Measure the String: Once you've found the right spot, remove the string and measure it using a ruler or tape measure. This measurement will give you an indication of the length to order.
