Well, I think it is admirable that someone is setting standards. It really bothers me (maybe my military training, maybe my OCD acting up) when people are willing to accept less than acceptable standards.
For example, it bothers me that the school is willing to accept the kids not dressing within the dress code. Granted, some can take it too far, but I think NO BARE MIDRIFFS and STRAPS MUST BE TWO INCHES WIDE is pretty clear.
At the hospital, I cringe when nurses are wearing fake nails. They are against dress code and they harbor all kinds of bacteria which can put patients at risk. I actually requested that a different nurse take care of my preemie twins cuz she had fake nails and she was a smoker!
I know this woman seems a bit over the top (and I think she is with the costume thing), but setting these standards may help your daughter learn a good life lesson.
I'm glad she likes it. I used to love to watch the baton twirlers at football games--especially when they played with the fire batons!
