Karada is a rope harness generally used in BDSM to bind a submissive/bottom in preparation for sexual play.  Karadas refer specifically to a type of rope harness that wraps around the torso and back and cross tightly through the groin area. 

Karadas are not used in suspension bondage or suspension play, rather they are intended as a from of bondage binding the bottom/submissive in either a standing or lying down position. 

Frequently Karadas with their decorative designs are used as erotic clothing.
