Abstract
Professional attire has traditionally been regarded as a sign of ethicality. However, recent trends towards a more casual workplace may have altered the general public's attire-based perceptions. To determine whether these trends have rendered the association between professional attire and ethicality obsolete, we draw on signaling theory and we examine, in two laboratory studies with working samples, the main effects of attire style (i.e., business formal, business casual, casual) on perceptions of employee ethicality. We also assess the mediating effects of attire appropriateness, the moderating effects of context (industry type), as well as their combined moderated-mediation effects in the relation between attire style and the outcome of interest. We find that casual attire is perceived as less ethical than business casual attire in both studies but is perceived as less ethical than business formal attire in the first study only. Moreover, the effect of attire style on perceptions of ethicality is mediated by perceptions of attire appropriateness. Lastly, we found inconclusive results for the moderated-mediation model, which suggest a more intricate effect of industry type than originally proposed. Three subsequent focus groups with working professionals provided additional insights into our findings and revealed workplace-relevant outcomes associated with perceptions of ethicality. Theoretical and practical implications, study limitations, and future research avenues are discussed.
