Japanese indigo dye, called aizome, began in the Edo period (1603–1868). Back then, only the upper classes wore bright colors and silk, so common people used cotton and indigo dye.

Today, aizome remains important in fashion and culture across Japan. 👘💙 [Source] @googlefactss#JapaneseIndigo#Aizome#EdoPeriod#Craftsmanship#History
