Tell us what you
REALLY think, Norm

Seriously, how are all the staff going to decide what's formal? Is a prom dress formal, but silk pants and a "sparkly" blouse, not? Will they have pictures of formal dress to go by and to show us how to dress?
What about the people who opt out of formal night and eat at the buffet? Are they not allowed to go to the lounges or the shows unless they dress up?
If they throw the "offenders" off the ship at the next port, are they also going to throw off the people who drink too much, smoke in non-smoking areas, let their children run wild and get into the adult hot tubs, save seats, etc., etc..
If so, you
will be on the ship alone

!
I say
enforce the dress code in the dining room and let the rest go.
