Firstly - I'm really late on this thread but in response to the first picture - it is not really acceptable but I doubt she MADE her daughters dress like that - they probably wanted to wear those tops - maybe they should have worn a vest top or something underneath though.
I can understand why they want to dress up to go out and 11 is an odd age - her daughter doesn't want to be a little girl anymore. I think they look okay in the last photo - it is more the posing rather than the clothes - why do they have to pose like that!?
Lourdes Cicconne doesn't pose like that and look who her mother is!!
