This study explores the roles of digital marketing (DM) and green marketing (GM) in promoting sustainable consumer attitudes (SCA) within the fashion industry. As sustainability becomes a focal concern for businesses and consumers, companies increasingly use digital technologies and GM strategies to enhance positive SCA. Depending on the quantitative research method, data were collected from 116 fashion-conscious consumers using an online survey and analyzed via the SPSS through factor analysis, reliability testing, correlation, and regression. The SCA are measured through its three main dimensions: environmental, social, and economic. Results revealed that the three independent variables, DM, GM, and social media marketing (SMM), positively influence SCA. DM marked the strongest influence as it affects all three sustainable dimensions, however, SMM and GM significantly influence the environment dimension, and not social and economic. Further studies should be conducted on long-term relationships, cross industry comparisons, and qualitative studies to investigate sustainability and consumer behavior further.
