Alexandre Gervais

There are many different types of women’s obi, and the usage of them is regulated by many unwritten rules not unlike those that concern the kimono itself. Certain types of obi are used with certain types of kimono; the obis of married and unmarried women are tied in different ways. Often the obi adjusts the formality and fanciness of the whole kimono outfit: the same kimono can be worn to very different situations depending on what kind of obi is worn with it.Wikipedia
