I showed the picture to 3 people at work and all 3 were clear that this is not a dresscode for school. To go out, fine... but not to school. And all 3 women have kids, some going to high school or college. They said that the skirt is fine but the top is too bra-looking, not enough covering and inappropriate for school and that the school was right in sending her home to change. This can be a huge debate and I can see why it went on the media.
I see it like one person's freedom ends where another's begins.

I wonder if the way we "read" how people should or not dress is not something "local" to their area.
