I think she looks alot better these days.. a much improved appearance from the US Open 2004... her short hair looks alot better, I wouldnt say she's the greatest in the world, but she's definitely not horribly UGLY anymore..
Well, you know how when you hear a song and hate it, and that song drives you crazy, but eventually you find that one day you kind of like the song? Well, your ears just deluded you into liking the song to avoid the pain.
Kuznetsova has quite harsh features so when she used to pull her hair right back it really exposed her large nose, mouth, jaw etc.
With her hair loose with that hairband she looks much better because it softens her face a lot. Somebody like Schiavone is similar because she can quite manly on court but i've seen picutres of her with her hair loose and she looked very nice and feminine.
i'm no stylist but as a red blooded male i certainly notice how important a women's hair is to them.
