A chubby baby is cute, but a great number of women would take offense to being called "chubby". Especially when they're not chubby by any normal standard. Do you think that So-Youn would like being called "chubby"? Replace it with f.e. "athletic" or even "curvy" everyone should be satisfied.well I am just be realistic here. do NOT support anorexic looking skaters. let us be honest, in figure skating, people appreciate lines and what is the reality of aesthetics in main stream Figure skating. no need to starve, but could use better costuming. BTW, Chubby is a cute word and considered very attractive in Japan.
As for the back design, I think, they are going for the greek goddess look. I like the idea and it is appropriate for the theme of song. but could designed better. just my opinion.
