The purpose of this study is to derive data that can implement a specific design and appearance through experiments to create a virtual sample as close to the original as possible. A literature review was conducted on the 3D Virtual Fashion CAD program and CLO, which is the most widely used program in fashion companies. We then conducted a survey of practitioners on the use of 3D Virtual Fashion CAD programs. This was done to demonstrate the fact that thin fabrics are implemented differently from the actual, and that hoods, sleeves, and flaps are applied with the most variation in regard to structural aspects. The subject of the experimental study, anorak jumpers with a hood of thin, rustling, woven fabric most commonly made of softshell fabric was created in two designs. The experiment identified the material of the sample which was made of three fabrics and created a virtual sample property value based on the designated basic property value. This was done to determine what property value was most similar to the sample after consultation with an expert. After applying it to the virtual sample as the final property value, an expert survey was conducted to evaluate its appearance. The results revealed that the basic property value input to CLO is light and thin and that it is not possible to accurately apply a material with a rustling appearance. The difference between the actual sample and the one shown in the virtual sample was quite noticeable with the virtual sample demonstrating problems including the collapse of the shape, amount of wrinkles being tilted downward, and the flap lifting on the body plate. This problem was found by adjusting stretch, bending strength, buckling, and buckling strength, as well as using rules for controlling physical property values according to fabric and design.
