Kimonos

A Kimono is is a Japanese traditional garment worn by women, men and children. The Kimono used to be a daily wear in Japan during the Heian period. They were influenced by Chinese han clothing which are today known as hanfu. Traditionally, kimonos are sewn by hand, but even machine-made kimonos require substantial hand-stitching. A woman's kimono may easily exceed up to $10,000 in US dollars. A complete kimono outfit, with kimono, undergarments, obi, ties, socks, sandals and accessories, can exceed up to $20,000. By the 1900's Japanese people started to wear more westernized attire. Kimonos are still worn today during tea partys, by modern Geishas, at funerals and during the summer they usually wear a modern form of Kimono now known as Yukata.
Kimonos are so fancy and cool I wish I owned a few.
