Plenty of skaters go darker when skating to latino music, so maybe that's why she changed to a darker tone. (I don't think it quite qualifies as black.) She may have also just wanted something different. I think the colour change was also more noticeable because her style for the FD was very plain-just a pony tail. She usually has it done a bit more elaborately.
I also preferred her 4CC dress. The new one was nice, but didn't seem to be tailored quite right for her figure. She does look great no matter what, though.
Serious, I was also mesmerized by her hip movements, and I'm female. That woman can move.
