1. If it's tied with something that I would allow in the hair, I don't mind it on the shirt. However, the number needs to be visible without obstruction.

2. The girls seem to like their spandex shorter, for some reason. However, they're still wearing them as intended (just shorter), so I wouldn't/don't mess with it.

3. So long as the number is visible, again, no problem.

Unlike the libero jersey, if you're not sure if it's not legal, it's probably ok.
