Finding your size

The easiest way to find your size is to wrap a peice of string and wrap it around your wrist ankle or neck.  If you want it snug, add a 1/2 inch.  If you want it comfortably loose, add 1 inch.  If you want iot really loose, add 1 1/2 to 2 inches, but bracelets this large may fall off.

Here are the typical sizes for the average person:

Bracelets
The average women's wrist is 6 - 7 1/2 inches, sometimes 8.
A man's is 7 1/2 to 8 1/2, sometimes 9.
For ankle bracelets, just add an extra 1 to 1 1/2 inches to your wrist size.

Necklaces
Necklaces have a wide range of sizes that are just a personal preference.

Chokers
Women : 12 - 14 inches
Men: 14-16 inches
If you work out a lot and have a larger than normal neck, add an inch.
