This one was not really an inspiration...it was a 'direct' passing down of costume. Yes, Mao at that time was wearing the SAME costume by Midori. It was kind of like a tradition to pass down used costume among Japanese skaters (esp. ladies' skaters around Aichi area). There were cases such as Mao passing down her costumes to Kanako, and then Kanako to Mako(?) or other younger skaters maybe. Also I think some younger skaters from Howa Sportsland got to wear Akiko's dress. Not to mention there are also cases when sisters can share costumes since both are in skating.
I remember Mao said in the interview later on that the costume from Midori gave her a lot of power when skating.

Though I have never seen any credits given for the inspiration (but it seems that someone in Kolyada's camp took a close look at what Javi was doing).
