A possible workaround is to give your sims an embarrassing formal outfit to wear for this purpose. Formal outfits aren't used much in the game unless you have a restaurant with that dress code. But party outfits can be used instead for that purpose. A well chosen party outfit can be good for restaurants, nightclubs, etc. Formal outfits are extremely optional and might be better reserved for the purpose of making the Simray work better. Unless, of course, you throw a lot of formal weddings for your sims. Then I think formal outfits become a lot more important. But if you just elope, no problem. Or if you set up all of your married couples ahead of time using the CAS system. That's pretty much my approach.
