A dress code is a set of guidelines that dictate what clothing is appropriate for a specific setting or occasion. These guidelines can vary widely depending on the context, such as schools, workplaces, or formal events. Common dress codes include business casual, formal, and casual, each with its own expectations regarding attire. Dress codes are often implemented to promote a certain image or maintain a level of professionalism. For example, a corporate office may require employees to wear suits or dress shirts, while a school might have rules about uniforms or appropriate casual wear. Adhering to a dress code helps create a cohesive environment.
