This is severe Kimono regulation and no matter how hot in May (especially these global warming days!), if you wore single kimono with summer sash, a member of committee of Kimono discipline (usually old nagging ladies) walk to you and warn.
Now June starts. This is my June style. Do you like them?
Single silk komon(dyeing) kimono
Gauze silk summer sash with fan and dragonfly motif
Violet cotton and hemp kimono under
Rose and orange silk sash scarf
Violet sash belt
Thanks for your comment, Satoai-san. I found this gray/white lattice kimono at a famous antique kimono collector Ms. Shigeko Ikeda's shop in Tokyo. This is the only one she praised me although I had tried tons of kimonos!
