ya, that bra strap rule is crazy! - it's like it's gymnastics, things move!
tell them about the nail polish rule!! you can have clear nail polish but not colored nail polish, but you can spray color your hair to match your leotard! lol :D I asked about it, and one of the coaches said it's because colored nail polish is distracting.....it would make a bit more sense if it was so that you could tell what color your nail turns if you jam or sprain it somewhere, or something like that!
...and you can paint your face and put glitter on, ...it's just a bunch of old rules.
