collars

In BDSM, a collar is a device of any material worn by a person to indicate their submissive or slave status in a BDSM relationship. A person wearing a collar to symbolize their relationship with another is said to be collared. Collars are used to signify ownership or connection within a Dom/sub relationship. The collar may also be worn by the submissive as a visual indication to others.
Collars come in many forms, from practical leather straps to elegant metal chokers or chains. The choice of collar can reflect the personalities and tastes of the dominant and submissive, as well as the nature of their relationship. For many, wearing a collar is a deeply meaningful act that symbolizes commitment, trust, and the power dynamics between partners.
Some submissives may wear "day-collars". These are typically items of jewellery (though can be any item of clothing) containing an O-ring. They are frequently used in scenarios in which it would be inappropriate for the submissive to be collared but their dominant wishes for them to be collared.
