I don't think a "carrot" approach will get players to obey a dress code.
You need a "stick".
Like a prize for best-dressed... a lot of guys will think
"Well I'm in no danger of winning that so I won't even try".
Then you end up with a lot of players still looking like slobs
because their nicest clothes are dockers and not a tux with vest.
But you can disguise a stick to look like a carrot.
"$15 discount on your entry fee if you show up meeting all dress code requirements.!"
Which is really a $15 penalty on those who refuse to get with the program.
