I think it might be a couple of those things, especially #1. Two of Nuri's brothers were groomsmen. We actually haven't seen any pictures of the bridesmaids right?
Jill just doesn't have any good taste, so whether the wedding budget was $200 or $5,000 it would've probably been a sad, sad affair.
Another poster elsewhere mentioned that of course when Jill had her vow renewal she got a new dress, real flowers and a nice cake? (I don't remember). Yet, her eldest daughter got fake flowers, a thrift shop wedding dress from the 80s/early 90s and some small homemade cakes. They got stimulus money for the kids and probably chose to spend most of it on unnecessary chotcki's for the house rather than put some of it towards the wedding. For fundie courtships, they waited a while to have the wedding and this was the best they could do?
