Answer:
One of the oldest U.S. Supreme Court traditions is the wearing of judicial robes. Justices of the Supreme Court have been wearing black robes since the early 19th century, which has become a symbol of their authority and impartiality. The tradition of wearing robes is believed to have originated from the practice of English judges wearing robes, and it has been followed ever since. The judicial robes create a sense of tradition, formality, and solemnity in the courtroom. They also help to distinguish the justices from the other participants in the courtroom, such as attorneys and litigants.
