1. An on-line garment fit portrayal system configured to operate on a specialized internet server located anywhere and linked over any network including the internet to at least one web-enabled player device located anywhere and capable of common image format display, the system comprising: a server-side garment model storage capability containing one or more garments, with parameters for each garment chosen from the groupings that include a garment piece parts list, piece spatial properties, piece mechanical parameters, piece optical parameters, and assembly information; a server-side modeler mechanism configured for generating a three-dimensional model of a subject's body suitable fix garment fit portrayals from an individual's registration data, the resultant model being represented by body data stored in a body model storage capability; a server-side simulator mechanism operatively coupled with the garment model storage capability and the body model storage capability for simulating a three-dimensional form fit of a garment represented in the garment model storage capability onto a body represented in the body model storage capability, the simulator mechanism producing a portrayal subject model; and a server-side rendering mechanism operatively coupled with the simulator mechanism for portraying a perspective view on a web-enabled device's display screen of the portrayal subject model representing a three-dimensional form fit of the garment on the subject's body.
