There is a very interesting and thriving kimono community on Instagram. As one would image it is largely based in Japan, and is rich in photos. From time to time we discover a Instagram account with some amazing kitsuke! In particular the Instagram account for Yukari is full of obi that are mind blowing awesome and rather complex.

Here are just a few photos from the account, prepare to be impressed.
