The popularization of new technologies, such as 3D Simulation programs is an important factor to help speed up the development chain and save resources within the clothing industry. Proper fit to help size conformity, company loyalty and to decrease return rates is becoming an increasing requirement. This study aimed to investigate the effectiveness of 3D virtual fitting technologies of garments and analyzing the similarities as well as differences between real and virtual fit.
Within this study different garments on the upper and lower body were analyzed and compared, by evaluating the whole development chain. The first step was to scan different test subjects with individual body shapes and figure types in the Vitus Smart XXL 3D Scanner and to generate according avatars for each size analyzed (a small, middle and large size). Then patterns were created for each garment and simulated virtually on the according avatar within three different 3D Simulation programs: CLO 3D, Vidya Assyst, and V-Stitcher Browzwear. These same garments were also sewn physically and fitted on the same test subjects to evaluate the similarities and differences between the virtual fit and physical fit.
The analysis showed that for both the virtual fit testing and physical fit testing in-depth fit knowledge was essential to evaluate the results properly. Sufficient ease and proper fit was given virtually in the example of this male jacket German size 50, which was simulated in CLO 3D. However, the ease was not sufficient enough when creating the physical garment and could not be closed, or small movements such as lifting arms could not be made, resulting in a too tight real jacket. Folds and tension will show on the physical garment, but not within the 3D software. An important insight was to simulate with base layers, as it would be worn in real life, since without base layers the fit was not shown accurately within the 3D system.
The investigations revealed that there are various factors that affect the success of virtual fit testing, This is an important research effort for the clothing industry, as it demonstrates which parameters need to be taken into consideration for a realistic and accurate virtual fit testing with the help of 3D technologies.
