Sims should now show up in their appropriate attire for Wedding Ceremonies
Fixed in Patch 1.85.203/1.55
If you're still experiencing this issue, please create a new thread.
A possible fix, though not an ideal one, is to download mc command center. I don't have it, but I'm pretty sure it has an option to force sims to change. If you have get to work, I think one of the scientist rays has an option to force sims to go formal as well. I don't have either of these, but they should work from what I've heard. Granted, it would be nice if the game actually just worked, but it's the sims 4.
I think it might be the Dresser module of MC Command Center that lets you force change Sims on the fly. So you'd only need it and the main modules as a temporary fix. This is a real mess though!
I suspect part of the issue is that setting the cake, dress code, formal wear tab in wedding planning does not actually save correctly, at least from the testing and experimenting that I have done.
