The rapid growth of social media has fundamentally transformed marketing communication strategies in the online apparel industry. Brands may influence consumer views and trust by interacting with consumers through social media platforms like Facebook, Instagram, and Twitter. The current study looks at how social media engagement metrics affects the development of customer trust for five Indian online clothing brands: Craftsvilla, Voonik, Limeroad, IndiaRush and Stalkbuylove. The study examines important engagement metrics, such as the quantity of posts, reactions, comments, likes, favorites, and tweets, using a quantitative research design and secondary data gathered from official brand accounts. Multiple regression analysis is employed to test eight hypotheses relating social media to customer trust across platforms. The findings reveal that posting frequency and consumer interaction metrics significantly influence trust formation, though the magnitude of impact varies by platform. Facebook engagement through reactions and comments strongly contributes to trust, Twitter engagement emphasizes responsiveness and immediacy, while Instagram engagement highlights the role of visual approval through likes. The study contributes to the existing literature by providing a comparative, multi-platform analysis of trust generation in the context of online apparel brands in an emerging market. For fashion marketers looking to maximize platform-specific social media tactics in order to establish and maintain customer trust, the findings provide insightful managerial implications.
