What is a "jupon"?

A jupon is a type of tunic that was worn over armor during the Middle Ages. It was typically made from sturdy materials such as leather or heavy fabric and was designed to protect the wearer from the heat and chafing caused by their armor. Jupons were often decorated with intricate designs or emblems to display the wearer's allegiance or rank and were commonly worn by knights and other nobles during battles or tournaments. Over time, the jupon evolved to become a more decorative garment worn over civilian clothing and was often worn by courtiers or wealthy individuals as a symbol of their status.
