A dress code is a set of guidelines that dictate what clothing is appropriate for a specific setting or occasion. These codes can vary widely, from formal attire required at events like weddings to casual wear allowed in everyday workplaces. Dress codes help create a certain atmosphere and ensure that individuals present themselves in a manner that aligns with the expectations of the environment. Common types of dress codes include business casual, formal, and smart casual. Each type has its own standards; for example, formal attire often includes suits and dresses, while business casual may allow for khakis and polo shirts. Understanding these codes is important for making a good impression.
