I do not know what the mothers are thinking. We have a family with two girls who are getting into their early teens. The older one has been wearing little girl "heels" and other fancy-type dresses since she was 8-9 years old. Now she is about 14 and wears skin tight leggings and shoulder-baring tops.
Until this moment, I hadn't really put it together that the little girls who like overly colorful, fancy type dresses when they are little will likely graduate to the inappropriate outfits in adolescence. It seems to foster an inordinate amount of self focus and attention to what other people are wearing.
In this case (above), the mother is not fashionable and sometimes dresses immodestly because something doesn't fit her properly. She favors dark colors (brown, gray, black) and sensiblewalking shoes and no makeup, no "hairstyle" per se.
The daughter is one extreme and her mother is another it seems.
