Wearing an advocate gown is generally considered an important part of a lawyer’s professional appearance in court, but whether it is mandatory can depend on the rules of the specific country or court. In many countries, including India, advocates wear a black coat or gown, a white shirt, and a white neckband when appearing in court. This dress code shows respect for the legal system and maintains the dignity of the profession. It also helps identify lawyers in the courtroom.

However, some courts may have relaxed rules in certain situations, allowing lawyers to appear without a gown, especially in informal or administrative hearings. Despite this, most lawyers follow the traditional dress code to maintain professionalism and uniformity. Not wearing the gown when it is required could be seen as disrespectful to the court or against the rules of practice.

In short, wearing an advocate gown is mostly mandatory in formal court proceedings, and it is considered a symbol of respect, discipline, and professionalism for lawyers.
