Perhaps a comment to the principal would be in order. It would be especially meaningful for your daughter to express her disgust also. Everytime I have doubts of whether or not faith-based private education is worth the money, I just have to hear about these little annoyances and I'm grateful for the policies the administration has over the school.

Btw, I've read many reports that modesty in clothing is on the way back in fashion. Hopefully we'll see less midriffs and more age-appropriate dress. sigh!
