Business casual is a dress code meant to encourage a certain standard of attire at workplaces. It often suggests a person should maintain a professional appearance that's relaxed and comfortable. However, a general agreement has not been reached about how to define the term.
Factors that determine what constitutes a business-casual dress code at a workplace vary due to many things, including the industry, the size of the company, how many employees work there, how often the employees interact with members of the public and norms of the corporate culture. Failing to understand and abide by a dress code could adversely affect how a person is perceived.
