H is for Harness

From Wikipedia (really cool pic omitted)

A bondage rope harness, sometime also referred to as a bondage web, rope web, rope dress or karada, is a bondage technique involving the tying of an intricate structure of rope around the body in a complex web-like fashion.
Similar in effect to a leather bondage harness, a bondage rope harness is not in itself normally used to bind a person, but it does apply pressure over the area bound and can be used as a securing point for other bondage techniques, including suspension bondage. It is not normally used to bind the limbs but you can bind the arms into the harness by simply going around the arms not under, as shown in the picture. A rope dress is often used with, or integrated with, a crotch rope and/or a shinju ("pearl") breast harness.
A rope dress typically takes around 10-15 m of rope to tie, and involves multiple passes of rope from front to back around the body to build up the characteristic diamond-shaped rope pattern, typically starting from a rope halter (as in the illustration) and moving down the body. In some cases, a rope harness may extend beyond the torso, into diamond-patterned webs that extend down the length of the arms or legs.
The Japanese term karada means simply "body". Traditionally, a distinction was made between kikkou ("turtle-shell" pattern; hexagonal) and hishi (diamond) patterned ties, although many modern sources just use the term kikkou to refer to any rope body harness.
