It's by Yves Saint Laurent - LOVE that jacket. I was thinking it would be by one of the Japanese designers like Kawakubo or Yamamoto (and not just because it's a ~kimono~ jacket, but because it's all structural and asymmetrical like they like to do) but apparently not lol.

... "Matsumoto Jun" and the fashion credits are the only thing I can read XDDDDDDDDDDD
