I suppose she just really likes the flats then, eh? I've never been much of a fan of her style, execept for the fact that it's radically different then what I'm seeing where I'm at.
As for the movies, out of the Trio, I think the character Ron is the only one spot on bookwise. Both Daniel and Emma are way off in my opinion. While she probably does have a say in what she wears, the studio most likely has the final say. Transitioning from the 2nd to the 3rd movie, there was a big difference in the clothing. Less uniforms, more regular clothes.
I'm still undecided on the hair issue though...
The interesting thing about her style is that in candid photos of her, she usually looks pretty good. Her outfit at the U5 ball and that party that came out awhile ago. She looked good, but when she hits the red carpet, it doesn't work right. Although I do admit, I liked the pink outfit with black tights.
