This study investigated the levels of avatar realism required for users to perceive a virtual body as their own and identified optimal avatar design conditions for positive user experiences without psychological discomfort. Fifteen female participants engaged in an experiment involving 30 distinct avatar conditions, combining two facial feature variations, five levels of body representation, and three outfit types, while using a VR headset. Participants evaluated their engagement with avatars by considering facial features, senses of body ownership and body presence, and the reliability of virtual fitting. The study also explored how avatar realism influences likability and overall user experiences. Findings revealed that modest simplification of avatar body representations could elicit positive user responses and suggested key technical specifications driving these effects. The insights gained from this study provide a foundation for optimizing virtual avatar design and fitting systems, enabling more immersive and user-centered experiences in digital fashion platforms.
