Stays incorporated in a neck corset are specially made shorter, used to support the weight of the head on the shoulders, while its corset structure helps in maintaining posture by keeping the chin high and the neck extended.
Neck corsets are worn by both men and women, mainly in BDSM and goth subcultures.
They may be decorated, and may include other bondage elements such as locking closures and D-rings for attaching a leash, rope or other restraints.
