This study aims to examine the effect of fashion interest on self-confidence and to identify differences in self-confidence levels based on casual and modish dressing styles among Generation Z. This research employed a quantitative approach with a causal-comparative design. The sample consisted of 323 Generation Z students selected using purposive sampling. Data were collected using a self-confidence scale and a fashion interest scale, and analyzed using descriptive statistics, simple linear regression, and independent sample t-test. The results indicated that fashion interest has a significant negative effect on self-confidence. In addition, there is a significant difference in self-confidence between individuals with casual and modish dressing styles, where individuals with casual styles tend to have higher self-confidence. These findings suggest that excessive concern with fashion trends may negatively influence self-confidence, while a simpler and more comfortable dressing style supports higher self-confidence among Generation Z.
