While I personally would not wear tatty clothes to a place like Jiko, I wouldn't care if someone else did. And I definitely don't care what anyone's opinion of my attire is, either.
My situation is also different than other people's. I have not been at WDW with young children, so I had time to go back to my room for a quick shower and to change for dinner. People who have young kids with them generally plan their day according to their kids' schedule, and might not have that opportunity.
Other people may simply have different sensibilities than I do. Fine for them.
We always do what's right for us, and have a good time.
