Maybe it's time Disney just follow the industry leading Six Flags and do away with the uniforms altogether. We had a good run and the past is the past and Walt's ideas have run their course.
Buy a bunch of unisex, neutral, Polo style shirts with no logo and make the CM's buy their own khaki pants from Target or Walmart, on their own dime of course, and make it standard across the parks. Maybe if the budget allows it, make the shirts for AK green to give the impression of caring about the planet and make sure to tell the guests the reason why they got rid of costumes is to cut out the process of cleaning the multiple costumes and cut down on global warming. Most of the diehards/pixie dusters will buy anything the company tells them.
The CM's then will be responsible for cleaning their own shirts and pants, thus saving the company on water usage and power. It's a win win, I tell ya. I can just see the shareholders rejoicing in glee with the cost cutting.
