A bondage suit may also be referred to as a gimp suit.
Strategically placed zippers on most of these suits allow dominants to access certain areas of the submissive's body, including the breasts, genitals, anus, and mouth. Most importantly, a bondage suit will have a number of metal rings or anchor points to make restraining the wearer much easier.
More About Bondage Suit
Bondage suits can be made from a number of different materials, but they are most commonly made from latex, spandex, or leather. Latex and spandex suits are stretchier and therefore more form-fitting.
Leather, however, can add a more authentic BDSM element for some people, and it is much more durable. Some leather bondage suits even have straps and leather rings that can be used to suspend the wearer from the ceiling. Some suits may even have built-in harnesses to hold sex toys or other sensation toys.
