The traditional collar is a neck band, normally in leather, metal or rubber. Collars can vary widely – from the decorative to the purely functional and although often removable, some are a permanent fixture. In BDSM communities, the wearing of a collar generally signifies that the wearer is a submissive. Many submissives and slaves wear a collar to denote their status and commitment. It can be used to represent the relationship in much the same way a wedding band does, especially if the submissive is owned. Some submissives wear a “symbolic collar”, such as a bracelet or ankle chain, which can pass in vanilla situations. It is not uncommon for a sub to have several collars for special occasions.
