Employees are frequently advised to dress for success to build their careers. From the corporate perspective, employees who are well dressed are believed to form better impressions with colleagues, clients, and customers. Many companies create dress codes in order to gain the benefits of a professionally appearing workforce. Developing effective dress codes, however, can be problematic. In some cases, employees resist dress codes, and in other cases, dress codes rigidly associate more formal dress with increased professionalism (Haefner, 2008). In this article, the authors describe ongoing research about the professional characteristics projected by formal versus casual workplace attire. They also describe their research about preferences for company norms and standards regarding typical workplace attire. Their findings indicate that business students see strong contrasts in professional characteristics associated with the degree of formality in workplace attire. Formal business attire projects authoritativeness and competence, somewhat formal business attire is associated with productivity and trustworthiness, and less formal business attire is associated with creativity and friendliness. These characteristics are interpreted in similar manner across ethnicity and gender. (Contains 2 figures.)
