This paper takes the Lonicera pattern in Yungang Grottoes mural paintings as an example, relying on digitization technology, discusses the specific process of symbol primitive extraction, digital reconstruction and pattern generation of Lonicera pattern. Three-dimensional virtual technology is also used to establish a human clothing model, complete virtual sewing, fabrics, fitting, and other digital clothing production. Based on Marvelous Designer, virtual clothing design is carried out for the Nendoroid pattern symbol series of clothing, and 30 students majoring in clothing are selected to score the simulation effect. In the simulation evaluation of the robe, the mean value of all evaluation indexes, except for the appliqué, is at 7 or above, with the highest mean value for the overall silhouette. Evaluators rated the patterned accessories of the cheongsam (8.393) highly, while the collar structure had the lowest score (7.272). More than 60% believed that modernized clothing with non-heritage symbols could represent the country’s image, promote its culture, and carry forward its spirit.
