Yuka Sato definitely knows what she's talking about! I agree 100%; I'd rather see a plain outfit that doesn't distract and or detract from the overall effect of the program...than to see someone look like a black Christmas tree (as
Medusa put it

) which causes me to be almost entirely unable to see what they're actually doing.
Takahiko's costume was just as simple as it could ever be. This reminded me of Jeff who wore an extremely simple costume in his SP at Worlds 2008 (I thought it a practice outfit when I first saw it). I would personally prefer something a little bit more interesting. Yet, if a skater could charm the audience in the simplest costume like that, it is a real honor for him/her.
I wonder if this happens to ladies though. Imagine a lady skater showing up in a black costume of plain material and black tights with absolutely no decorations and no makeup on the face. Can she still be a contender?
BTW, when I first watched only Takahiko on YOUTUBE, I thought he won because Evan and Johnny failed. But after watching both, both did fairly well. So I think that Takahiko should be really proud of himself. He said that neither he nor others around him expected this so that he had no idea what to do. I hope that he would be a contender on the world podium (a bit too early to start talking about it though).
Yet, I still think that Johnny could have won; so could Evan. But Johnny planned and excuted less combos than he could have, which has been a wonder. I also wonder if Evan maxed his elements as planned.
ETA: I checked the protocol and it seems that the downgrade on 3A combo really hurt Evan. He also failed to put three combos because of the fall on the quad combo.
I don't understand why Johnny wants to plan a much lower base value than his competitors. He didn't miss many jumps, but he couldn't have beaten Kozuka with that jump layout unless Kozuka had failed.
I also wonder why Kozuka could not get higher levels on his steps even though he clearly looked so strong in steps. hope he could address this by the next event.
