"Dress down" is a phrasal verb that is more commonly used in informal contexts compared to formal speech. It has two primary usages. Firstly, 'dress down' is used to refer to the act of dressing in a more casual or less formal manner, often in contexts where a less formal attire is acceptable or encouraged, such as 'casual Fridays' at work or when someone is trying to blend in more casually with their environment. Secondly, 'dress down' can also mean to rebuke or scold someone severely. In this context, it could be used in both informal and somewhat formal settings, like a boss giving an employee a "dressing down" for poor performance. This dual meaning makes the phrasal verb versatile, although the context usually makes it clear which meaning is intended.
