This study examines how consumer characteristics–wellness, religiosity, and fashion consciousness–on the perception of modest activewear attributes and purchase intention among Indonesian consumers. It employed the FEA consumer model, which integrates functional, expressive, and aesthetic dimensions for clothing development. A total of 200 responses were collected from adult women in Indonesia through an online survey conducted from October 16 to 25, 2023. Using SPSS 26.0, frequency analysis, factor analysis, multiple regression, and reliability testing were performed. The results indicate that fashion consciousness and physical wellness significantly influence the functional elements of modest activewear, while fashion consciousness and religiosity significantly affect the expressive elements. Furthermore, fashion consciousness, religiosity, and physical wellness all have significant effects on the aesthetic elements, with fashion consciousness emerging as the most influential factor. In contrast, emotional wellness did not show a significant effect. Regarding purchase intention, functional and expressive attributes of modest activewear show significant positive effects, while aesthetic perceptions directly shaped Indonesian women’s purchase decisions. While prior research on modest fashion has largely emphasized religious motivations, this study advances the discourse by integrating wellness and fashion consciousness as equally important drivers. This study analyzes three consumer characteristics within the FEA framework, offering a unique perspective on how lifestyle, fashion, and religiosity influence modest activewear consumption.
