#026 jinbei uses "yagasuri" for the top body, "keshidama" for the sleeves, and "kumo" for the pants.
Yagasuri: The design is based on arrow ("ya") feathers, which has been around for centuries. As the pattern was used for women servants’ kimono at imperial palace, it's one of the representative traditional patterns. This stunning sky blue color was made only for the summer 2015 season.
"Keshidama" is an old tie-dye technique pattern (this one is dyed using a paper cut-out pattern), which appears in a book written in 1840s. "Kumo" means cloud. The cloud was expressed through various patterns since late 500.
