I'm guessing the "Party for the Senses" is some kind of special deal. I agree that code sounds rigoshdarndiculous for WDW, but I'd like to hear more about what it is first.
As for the rules in general...
I understand not allowing these:
...torn clothing, swimsuits or swimsuit coverups... tank tops
The rest, however...
flip flops...hats... and t-shirts.
... is taking things a little too seriously, given the overall environment. Flip flops are no longer viewed as slum shoes by many and hats and t-shirts covers way too much ground for the restaurants in question, again, given the overall environment.
I agree with Pete, seems to be a lot about nothing. Are that many people really showing up in torn shorts and wife beaters at the California Grill? Or string bikinis at Jiko?
From a practical pov, is Disney really going to turn away a family who has one member wearing flip flops with their sun dress, or a clean Mickey Mouse t-shirt with their Dockers shorts?
My guess is they just want to post the code to ensure that most people dress reasonably, and they have no intention of turning anyone away unless its a "grevious" offense.
Me personally? The only things on that list I'd even consider wearing to those restaurants are the flip flops and a t-shirt, but that's just me. And I have no desire to have Disney start telling anybody else they can't wear something just because I wouldn't wear it there. In fact, if the ladies want to start wearing bikinis to the restaurants, I enthusiastically support their decision.
