Kimono is Japanese traditional clothes. Furisode is one of the kimono and it is wore by somebody who are not married.
Furisode has long sleeve and wholly designed Kimono. It is very beautiful and basically wore by young women who are not married which is a rule of Kimono. Once you get married, women usually do not wear them and wear different type of Kimono.
But since Furisode is very expensive and people do not have many chances to wear Kimono, even married women wear them at friend’s wedding recently for not to waste.
