Recently, fashion and luxury markets in Asia have grown rapidly. In order to effectively predict fashion consumer behavior, the objective of this study is to propose and evaluate the concept and dimensions of a consumer's fashion readiness. After collecting data from 365 consumers in Taiwan, this study conducts confirmatory factor analysis to develop a 13-item fashion readiness scale, which includes four facets: fashion self-efficacy, fashion anxiety, fashion involvement, and fashion innovativeness. This study not only confirms the positive relationship between fashion readiness and fashion opinion leadership, but also provides support for the convergence among four facets of fashion readiness through a second-order confirmatory factor analysis. Finally, several academic and marketing implications for fashion readiness are discussed.
