It is a kimono that existed from ancient times, but it is said that it became the present shape after the Heian period. From ancient times to the Nara period, most of them were pants-shaped or skirt-shaped clothing and jackets or one-piece clothes.
However, in the Heian period, kimonos came to be made using a method of sewing the fabric into straight lines (straight cutting) without being bound by the lines of the wearer's body. In addition to being able to easily fold kimonos with straight-line bleeds, many kinds of kimonos were made, with various ideas such as layering when it was cold, and using cool materials such as hemp in hot summers.
In this way, the kimono of the present shape melted into the life of the Japanese.
