Most necklaces can be made into bracelets also, but may vary from the pattern used in the necklace.
Standard length of necklaces:
CHOKER- 15"-16" long and lays at the throat. Chokers look nice with open necklines and work well with button up blouses as well.
PRINCESS- 18"-20" long and falls lowers than a choker. It feels relaxed and works well with high nicklines, like turtle necks, and also very low necklines.
MATINEE- 23"-27" long and falls mid-chest. This length works well with most necklines, except very low necklines.
LARIAT- 36"-42" and falls very low, usually past the bustline. This can also be double looped around the neck.
NOTE: Where your necklace falls on your particular body will be affected by the size of your neck and the size of your bust (for longer styles).
