Very interesting, thank you!
So here's from LA to Tokyo and NHK short doc on Satomi Ito, the best known Japanese figure skating designer. She became a big name in the business designing 30+ costumes for Yuzuru Hanyu but worked also with Shoma Uno, Mao Asada, Satoko Miyahara, Rika Kihira, Mone Chiba, Kao Miura, Shun Sato and Yuma Kagiyama, but also with foreign skaters including Zhenya Medvedeva and Ilia Malinin, and many many more. I believe she's the designer behind current Olympic costumes of Mone, Yuma, Shun, Kao and Ilia.
This is NHK World so fully subtitled in English, enjoy
