This neck corset is made out of beautiful black leather with feather trim and a beaded accent along the edge. It is laced in the back with black satin ribbon. The front of the corset has spiral steel boning. The corset is pictured here on a mannequin with a 14" neck (measured around the throat). The lacing does allow it expand quite a bit. While the leather this piece is made out of is soft and pliable, it is a posture collar and meant to keep the wearer in a position with their head up and shoulders back. Note- This item can restrict blood and airflow if laced too tightly. NEVER tight lace a neck corset and do not double knot the lacing in such a way that it cannot be easily undone.
