Which one has the better fashion sense?

Both are known for the voice, looks and personality but what about fashion which one do আপনি think has the better fashion sense (on and off stage). Personally I think both Cristina and Amy amazing fashion sense. Amy started with what I call mixture of goth/punk/fairy/rock style that later changed to a mature/romantic goth look. I think she wears kind normal/causal clothes off stage. Cristina seemed to have a modern kind of style that is a mixture of goth/alternative later wearing আরো Milan high fashion. I had often wonder if either singer would some where down the line create their own fashion line. What would it feature? Would it be reasonable? Would there be a spin off line? Etc
