This study digitizes ethnic clothing design from the perspective of fine arts. The female human body data obtained is uploaded to the corresponding design platform of Style3D, and the design resources are precipitated to form a corresponding database. The virtual fabric drape parameters and virtual fabric control parameters are utilized to achieve 3D virtual fabric drape simulation. Combined with the results of the ethnic style recommendation configuration to obtain virtual samples and evaluate satisfaction. The results show that the bust, abdominal, and hip circumferences of the acquired female body data are within the ranges of 42-52cm, 40-57cm, and 47-49cm, respectively. The results of the draping simulation experiment showed a smooth state after 90 minutes for six different fabrics. The highest similarity between length and width between the upper and lower bodice and pants was found for lapel bodices (0.9) and slouchy bodices (0.88), respectively. These correspond to long gowns with large lapel bodices and pants. Designer B’s highest mean value of 4.67 indicates that designers are highly satisfied with the ethnic clothing design function of Style3D, as the mean values of the six styles are above 4. To sum up, this paper advocates for the application of ethnic clothing design using Style3D technology.
