Kimono are made of silk and normally very expensive though there is now a thriving market in second hand kimono. Nowadays they are worn at formal or traditional occasions such as funerals, weddings or tea ceremonies. Kimono differ in style and color depending on the occasion on which it is worn and the age and marital status of the person wearing it. To put on a kimono needs some practice. Especially tying the belt (obi) alone is difficult so that many people require assistance. Wearing a kimono properly includes proper hair style, traditional shoes, socks, underwear, and a small handbag for women.
