She is only 6! You can't really see her personality at this age but in 10 yrs we will!!! ;p
I've been reading your comments. My god, could you be more superficial? Who cares what the child is wearing, as long as the clothes are clean, fit and right for the temperature? It's just clothes. She looks happy, smiling and having fun on most of these pictures. And that's all that matters.
The fact that people like you find individual expression sad is what is REALLY sad.
