Clothing, as a powerful tool of self-expression and social identity, significantly influences perceptions and interactions with others. This research aims to explore the impact of different clothing styles on social interactions and helping behavior. In the first study (n=57) we explored the stereotypes and prejudices of four common clothing styles (i.e., Bohemian, Classic, Elegant, and Sportswear) using a verbal association task. We then investigated how bystanders (488) interacted with, and even helped an unknown individual regarding their clothing style. Our findings suggest that clothing style can significantly impact social interactions, with more formal styles, such as Elegant, leading to increased social engagement. However, prosocial behavior did not appear to be influenced by clothing style. This research highlights the complex interplay between clothing, identity, and social behavior. It emphasizes the importance of understanding the psychological and social factors that drive clothing choices and their subsequent impact on well-being.
