CHOKER

A 'choker' is a tight-fitting necklace, worn high on the neck. This type of jewelry can consist of one or more bands circling the neck. Chokers can be made of a variety of materials, including velvet, beads, metal and leather. They may or may not be adorned with sequins, studs or some kind of pendant and come in a variety of colours.
Some forms of choker are regarded as fetish clothing: see collar (BDSM).
