This study investigates the influence of the innovativeness of consumers on extended products in brand extensions. 300 surveys were distributed and 283 were used in the final analysis. The results of this study show that consumers evaluate similar product category (i.e., sportswear) better than a dissimilar category (i.e., cosmetics) in brand extension. In addition, innovative consumers evaluated extended product better regardless of similarity with the original brand. The results showed that consumers with higher level of innovativeness were less likely to evaluate differently between a similar product and dissimilar product categories in apparel brand extension.
