The method comprising steps for generating a garment by creating two-dimensional (2D) panels, in which the garment comprises a plurality of garment landmarks (GLMs) and a plurality of garment landmark lines (GLLs), which are key locations and lines on a surface of the garment, simulating draping of the garment on a reference body, where the reference body comprises body landmarks (BLMs) and body landmark lines (BLLs), performing a fit evaluation and calculating misfit measures comprising landmark (LM) misfits, landmark line (LL) misfits, and circumferential misfits, performing a fit adjustment for panel alteration operations modifying some of the 2D panels based on the fit evaluation, performing draping simulation with the modified 2D panels, and repeating until the misfit measures fall within a predetermined criterion and determining customized 2D panels that fit the reference body. ## Claims ### Claim 1 A method for automatic garment fit customization, the method comprising steps for: generating a garment by creating a plurality of two-dimensional (2D) panels for the garment based on a drafting scheme of a preliminary garment generation (PGG) system, wherein the garment comprises a plurality of garment landmarks (GLMs) and a plurality of garment landmark lines (GLLs), which are key locations and lines on a surface of the garment; simulating draping of the garment on a reference body, wherein the reference body comprises a plurality of body landmarks (BLMs) and a plurality of body landmark lines (BLLs), which are key locations and lines on a surface of the reference body, wherein the BLMs and the BLLs coincide with the GLMs and the GLLs, respectively; performing a fit evaluation and calculating misfit measures comprising a plurality of landmark (LM) misfits, landmark line (LL) misfits, and circumferential misfits; performing a fit adjustment for panel alteration operations modifying some of the plurality of 2D panels based on the fit evaluation in order to enhance the fit; performing draping simulation with the modified 2D panels; and repeating the above steps until the misfit measures fall within a predetermined criterion and determining customized 2D panels that fit the reference body within the predetermined criterion; wherein the plurality of 2D panels are generated in terms of data set in an information processing device and stored in an information storing device in the information processing device, wherein the plurality of 2D panels are configured to be displayed and manipulated on a screen of a display of the information processing device, wherein the garment and the reference body are configured to be displayed and manipulated on the screen, and wherein the preliminary garment generation (PGG) system and the drafting scheme are provided and processed in the information processing device; wherein the misfit measures are calculated and measured by discrepancies between the BLMs and the GLMS or BLLs and GLLs; and wherein the LM-misfit is represented by an LM-misfit vector eLM, which is a 2D Euclidean vector between corresponding BLM and GLM excluding surface normal directional component and obtained by projecting the GLM to a BLM-plane and resolving the coordinates with respect to a BLM-frame, and wherein the amount of misfit is calculated by the LM-misfit magnitude eLM−∥eLM∥. ### Claim 2 (depends on 1) The method of claim 1, wherein the LL-misfit is represented by an LL-misfit vector eLL of a circumferential or non-circumferential LL, which is a vector of a predetermined number of reference points (RPs) on the corresponding GLL, and wherein an average of the LL-misfit vector eLL is defined as the mean square root of the LL-misfit vector, which tells how well the Rps of GLL are aligned to the BLL-plane. ### Claim 3 (depends on 2) The method of claim 2, wherein about 12 RPs are used for each circumferential GLL and about 5 RPs are used for each non-circumferential GLL. ### Claim 4 (depends on 3) The method of claim 3, wherein a circumferential misfit ecLL is defined for each circumferential LL, and wherein the circumferential misfit ecLL comprises a scalar giving the difference in the circumferential length of a circumferential BLL and a circumferential GLL corresponding to a circumferential LL, the circumferential misfit ecLL, indicating how tight or loose the circumferential GLL is compared to the circumferential BLL. ### Claim 5 (depends on 4) The method of claim 4, wherein the fit adjustment is performed so that the LM-misfits and the LL-misfits are reduced in a shoulder line, a neck line, a bust line, and a waist line for a bodice. ### Claim 6 (depends on 5) The method of claim 5, wherein the fit adjustment is performed from top to bottom. ### Claim 7 (depends on 6) The method of claim 6, wherein the panel alteration operations comprise a point translation, an edge translation, a spreading, a contraction, and a dart edit. ### Claim 8 (depends on 7) The method of claim 7, wherein the fit adjustment performs the panel alteration operations when the corresponding BLM and GLM mismatch each other at the lateral neck and later shoulder.
