That seems like a lot of money, but if the parents can afford it, why not? In my experience, a lot of people don’t really do the sensible thing when it comes to weddings.
Speaking of musicians, the best one I ever attended was that of a jazz musician (F) I knew. His fiancee (V) told a group of us in a jazz club one evening that the date was set, but they were just going to the Courthouse, period. No guests, no family, nothing.
One of the girls from the group said that she had a beautiful dress that she’d only worn once, and that it would fit V. I asked the owner of the jazz club if he’d mind if we had a little celebration in the club. He agreed. Each one of the group agreed to bring a dish for a potluck sort of meal. Some agreed to bring flowers. The musicians who were there that night said that they would come and play, and let other musicians know of the event.
The club was beautiful, everyone had outdone themselves to bring in great food. Someone brought in a huge cake. The bride and groom were glowing. The music was just amazing. I can’t remember a more fun wedding, and I’ve been around quite a few decades.
BTW, I’ve yet to experience a very lavish wedding that I’ve actually enjoyed. I go to them out of affection or respect for the people getting married, the the proceedings are boring, and I would avoid them altogether if I didn’t have a sense of duty.
