No, just simple trousers and pullovers for the gentlemen and long sleaved simple one piece dresses for the Ladies.
I disagree with all the posters who claim it enhances the competitiveness. While fans, particularly ladies, enjoy commenting on costumes, no one ever said the costume made him/her lose or gain points. Costumes are not included in CoP.
I do believe that some costumes are a ploy to hide the inadequacies of a skater's technique. The skaters should work on technique and sell the program through skating. A little bit of understanding music would help moreso than the costumes.
I think an understanding of music is definitely something that would help skaters enormously. As far as I'm aware most skaters' off ice training will involve some form of dance or musical training which would focus on explanations of different musical styles and understanding movements that are appropriate.
Personally if that happened i'd stop watching (i'm already less enthusiastic about skating every year the season starts wince COP) altogether because it's the blend of sport and performance that I love about skating.
For me the "spirit of FS" is the combination of the physical technical aspect fusing with the performance art aspect of it. It is unique in this regard. That is what i love about it, and that is what , for me, is the spirit of FS. The costumes are part of the performance - a very small part of it, but a part nonetheless.
