However, SR aspects of products are difficult to verify by consumers. To help brands effectively communicate their SR efforts, this study assessed how consumers process an apparel brand's SR messages based on their prior experiences with that brand (brand schemas). Information transparency on messages and source of messages were tested as external cues to influence consumers' brand schemas and SR message evaluations in a mixed method repeated measures online experiment using a national US consumer sample. Results from regressionbased conditional process analyses indicated that increased congruity of consumers' schemas to the fact that brands are SR led to more favorable attitude toward brands' SR messages. Also, presence of high information transparency on SR messages influenced consumers' schemas positively, and in turn, they evaluated messages more favorably. However, consumers were not influenced by whether messages were made by brands or third-party organizations. The study results show the importance of brand schemas and information transparency on apparel brand communications, helping both apparel brands and educators create effective SR-related marketing strategies.
