Yeah I noticed that when after I seen the movie many times. All the other princess movies of where the princess and prince or leading lady & leading man gets married, they dont have wedding rings. I think its great they did that with Tiana & Naveen. Why did they never do that with the other movies? Did they have wedding rings in those time peorids or not?

yeah, it might be a time period thing, or maybe the animators just forgot. They pay so much attention to all the other details anyway, it just slipped their minds I guess
