A quick and simple definition (unlike the guy's up there)

A costume that one puts on that makes someone look like an animal. Usually used by furries and actors.

A fursuit style of costume is usually a elaborate full body costume constructed over a period of many months. The wearer may make their own costume or have another make it for them. They may be very elaborate and involve several different colors of fur. The head is usually sized to be more true to life.

There are several methods used to construct the head. Papier mache may be built up possibly on a wooden frame, but this usually results in a very heavy head. Foam blocks may be hollowed out and carved, then covered with fur. Plastic or fiberglass strips or wire may be formed into a frame and covered with papier-mache or other material. A hockey mask or other helmet may be used as a foundation to build a head.

The most elaborate heads are ultra custom made to form fit on a persons head. This is done by making a lifecast, or mold of a persons head. Lifecasts can also be made of the body and hands.

Some may apply one or more pieces of latex rubber, called prosthesis, shaped like muzzles or ears, to their head with spirit gum. The edges can be blended to the skin with some kind of putty or clay material. Then makeup can be applied over the prosthesis and face.

The body suit is usually constructed from several different colors and possibly lengths of fur. Usually there is belly fur of a contrasting color, usually light or white, reaching from the throat to near the groin. In come costumes, the zipper or other fastening is run along the seam between the belly fur ...
