On one hand, I agree that it is crazy for these type of deductions, and we have been discussing this at dd's gym. On the other hand, I can understand where some of it is coming from (now)
The finger/toe nail polish is a rule b/c if there is an injury, they want to see circulation to the extremeties, and it is difficult to do if the girls are wearing polish (at least, this is what I was told)
dangly/large or multiple earrings can be a safety issue...seriously, I guess its a wonder they even let them wear post earrings!!
The tight bodysuits and no underclothes showing, I was told this was a body-lines thing...bulk and bumps and wrinkles in the fabric can detract from the clean lines that the judges like to see.
Whether this is at all true or not, and whether we think its nuts or not, "rules is rules" I guess...
