A method and system for specifying the fit of garments and matching the fit of individual garments to individual consumers is disclosed. In one embodiment, a method includes categorizing human body shapes based on dimensional and demographic body measurement data sampled from the human population, and statistically analyzing the measurement data to determine the appropriate number of discrete body shapes, as well as the range of measurement values characteristic of each body shape. The method includes assigning to each body shape a shape code, which is a unique name and/or symbol and/or curve representing that shape. In one embodiment, a recommendation engine is employed to specify and match the fit of individual garments to individual consumers.
