The purpose of this study was to examine a hierarchical model of consumer innovativeness in the context of 3D fashion products. In particular, this study explored how different traits, such as personal values and innate innovativeness, predict a positive attitude towards 3D fashion products through domain-specific variables such as fashion innovativeness and fashion leadership. Using a convenience sample (n = 250), the data were collected through a self-administrated online survey. The results of this study identified personal values as an antecedent of innate innovativeness and found that fashion leadership played a critical mediating role between innate innovativeness and domain-specific innovativeness, in turn developing a positive attitude towards 3D fashion products which led to intention to use. Although the effect of innate innovativeness on domain-specific innovativeness (i.e., fashion innovativeness) was partially supported and no direct effects of personal values on domain-specific innovativeness was found, findings of this study contribute to existing literature on the Technology Acceptance Model and Consumer Innovativeness by examining additional predictors. The significant mediating role of fashion leadership was valuable as the result supported the key role of innovators as opinion leaders as discussed in the previous literature.
