A more thorough explanation:

Definition: A stuff gown is a type of professional robe worn by junior barristers who have not been appointed Queen's Counsel. It is also used to refer to a junior barrister.

Example: John is a stuff gown at the law firm, which means he is a junior barrister who has not yet been appointed Queen's Counsel.

Explanation: The example illustrates how the term "stuff gown" is used to refer to a junior barrister who is still in the early stages of their career. The term is derived from the type of robe worn by these barristers, which is made of a cheaper material than the silk robes worn by more senior barristers who have been appointed Queen's Counsel.
