Ok guys, I think all the TOs and PTOs could see the point here.
At tournamnets, esspecially ones in public places, people with their kids often come and check things out, sometimes even wanting to get a POP ID and start playing. Think about how many people would be turned away because they never knew Pokemon Dress Code existed because they never knew about the tournament.
*New kid walks by a game store where cities is being held*
*Kid walks in and asks the TO about what is going on*
*TO tells him, and he is interested in learning Pokemon*
"sorry", says the TO "but I can't let you play cause you have to dress properly, please come to some other tournamet to learn how to play the game."
Also, it's hard enough to get kids dressed up for church, BUT for POKEMON events....lol
I'm not trying to insult the OP, but this would be a horrible, horrible, horrible idea.
