What is the history of haori and how did it become traditional Japanese clothing for men?

The haori is a traditional Japanese garment for men that dates back to the Heian period, between the 8th and 12th centuries. At that time, the haori was worn by the aristocratic class to protect against the cold when traveling on horseback. Over the centuries, the haori became a more common garment, worn by all men, regardless of social class. It was especially popular during the Edo period (1603-1868), which was a time of peace and economic prosperity in Japan. At that time, the haori was often worn with a kimono for formal occasions. The haori has also become a symbol of belonging to a social group or profession. For example, samurai wore a purple haori on the outside of their armor to indicate their rank, while artisans and traders wore haoris with specific designs to identify their craft. Today, the haori is considered an important traditional garment in the Japanese male wardrobe. It is often worn for special occasions, such as weddings and religious ceremonies, as well as for cultural events, such as festivals. The haori has also become an inspiration for contemporary fashion designers in Japan and around the world.
