I love the fact that Michael said Aziraphale wouldn’t change his clothes for the ball.
I don’t know why Michael said that, but to me it looks like Aziraphale and Crowley were the only ones not under any spell or change - they were not part of the fantasy.
Aziraphale didn’t want Crowley to think they were acting, pretending, putting on a show. That it was fake.
Aziraphale wanted it to be real.
