Main Street Theatre, Vehicles, and WDW Railroad all still wear the navy vest costume. PAC, Glow, and Main Entrance ops and merch wear the new new blue/maroon outfit. PAC does the flag retreat and I agree, the new costume doesn’t fit the dignity of the show, but they needed an update as PAC spends their whole shift outdoors in the heat. Way back PAC would be made up of Cast deployed for a few hours from other areas to help with audience control and were not as likely to spend the whole day in outdoor positions. Now it’s a specific role.
