I totally agree! A costume is something you wear for a performance, not when you go to buy croissants in the local bakery in the morning. It should relate to the choreography, character etc. And that should never be forgotten.
Undoubtedly in figure skating from time to time we see athletes wearing something… disputable (I don’t think I’ll ever forget Domnina and Shabalin and their „Aboriginal” costumes from Vancouver) but I would never consider any of Yuzuru’s costumes fitting into this „category”. I saw people being surprised by Yuzuru’s costumes, sometimes even a bit put off by them, but I don’t think he is the first one to cause that reaction. I would say that Johnny Weir’s SP costume from OWG 2010 was more „shocking” at least to my friends that watch figure skating only when I tell them to do so.
Of course it’s a bonus when a skater has their own style in costumes. In a way I can say that Nathan has his own style too, although it’s a rather boring one ;- ) but tbh if he wore something more „creative” I would feel almost like he is cheating (and I even like his last FP shirt, but I suppose after the „scrambled eggs one” everything is an upgrade). Also, not everyone would look as good as Yuzuru in that kind of costumes that he often wears. Skaters have different body types and that should be considered too. Why would you wear a swan costume if you don’t look gracefully enough in it? Not a lot of men would be able to pull off that look! I think we just should be happy that there is someone that can do it in a very aesthetically pleasing way ;-)
