A barrister's wig is a traditional piece of legal attire worn by barristers in courtrooms, particularly in the United Kingdom and some Commonwealth countries. Made from horsehair, the wig is typically white or grey and features a distinctive, curled design. It symbolizes the barrister's role in the legal system and is often worn during formal court proceedings. The use of wigs dates back to the 17th century, when they became fashionable among the upper classes. Today, the wig is part of the formal dress code for barristers, along with a gown and white collar. While some jurisdictions have moved away from this tradition, the wig remains a recognizable symbol of the legal profession.
