This study examines visualization of fit of select garment designs on two types of virtual avatars: a personalized avatar developed through self-body scanning technology, and a selected avatar from a pre-programmed software program. The purpose is to increase understanding of the visual elements, accuracy and reliability of fitting simulations. For this exploratory comparative analysis, a purposive sample of design students designed five garments on a custom avatar using the Kinect system and an avatar selected from the Optitex computer program that most closely resembled the designer. Design professionals rated the appearance, smoothness and fit of the front, back and side views of each garment and avatar, and included qualitative comments. Results show a low range of difference but the pre-programmed avatar scored higher on appearance, smoothness and fit. Qualitative responses suggest the pre-programmed avatar is more aesthetically pleasing but the self scanned avatar showed more accurate body proportions of the torso and drape of fabric relative to the body. Implications for further research are included.
