What size do I need?
Wrap a string around your ankle, draping naturally, the way you would like an anklet to fit. Mark where the string meets, measure it and add 1/2 inch. Round up if necessary to the closest available size.
For gifts, 10 inches is a woman's medium, 10.5 is large, etc... (For a man, add 1/2 inch to the previous dimensions, i.e., 10.5 inches is a man's medium, 11 is large, etc...)
