Football jumper swapping during matches

this needs to be brought to the highest level of authority...
last saturday i played in a game where on more than one occasion a player who was coming off the ground took his jumper off, made his way into the changerooms, then whilst in there miraculously morphed into a player 2ft shorter and with different coloured hair.
The only difference on the jumper was a piece of strapping placed on the back to turn it into a 4 figure number, which subsequently lasted around 3 minutes before it fell off.
There are a number of issues with this including interchange steward issues, and umpiring reporting issues.
When i quizzed the offending bench re this i was given the explaination that it was not AFL and we didnt need to worry about that rule... WHAT OTHER RULES SHOULD WE DECIDE TO PLAY WITHOUT ON A GAME BY GAME BASIS!!!!!
This club in question fields a number of teams during the year, would be getting plenty of subs from all its players, and doesnt have the overheads of clubrooms to pay for, so why the hell can they not afford full sets of jumpers...
This is a disgrace, and needs to be looked at straight away otherwise there is no point in other clubs doing the right thing...
How ******* hard is it!
