Traditional Japanese clothing is called "kimono" in Japanese. It's a long robe-like garment that has been worn in Japan for centuries. They are mostly made of silk or other natural fibers and are designed in a way that is both comfortable and elegant.
The kimono is made up of several different parts. The main part is a long robe that goes all the way down to the ankle. The robe is usually made of a single piece of fabric, which is folded and sewn together in a very specific way to create the shape of the kimono. This fabric is often decorated with beautiful patterns or designs.
The sash that holds the kimono together is called an "obi." This is tied around the waist and is usually very wide and thick. It's often made of a contrasting fabric to the kimono, so it stands out as a distinct part of the outfit. The obi can also be decorated with embroidery, painting or other designs.
The kimono is usually worn over a basic undergarment called a "nagajuban". It's a long cotton layer that's worn under the robe. Women also wear additional undergarments for support and to make the shape of the kimono look more flattering.
The sleeves of the kimono are very wide and often very long. They are meant to be folded up at the wrist to expose the undergarment underneath. The style of the sleeves can vary depending on the occasion. For example, a formal kimono might have very long, flowing sleeves, while a more casual one would have shorter, more practical sleeves.
In Japan, the kimono is not just a piece of clothing, but a symbol of Japanese culture and history. It's worn on special occasions, such as weddings or other celebrations, and is often associated with refinement and elegance. Today, many Japanese people still wear kimonos for formal events or as a way of expressing their pride in their cultural heritage.
