The social pressure there is off the chart. People don't have a wedding ceremony for themselves it feels like, they have it for everyone else.
When we got married, people tried to pressure us. "You have to have a big ceremony so you can invite X, Y, Z and their kid and their parent and their cousin and blah blah blah".
We put our foot down. We did it for ourselves. We had <10 people over, it happened at a high end resort where we had plans for US (and told people they could do whatever the f* they wanted). Including hotel, plane tickets, the rings (while we did have the diamond ring, most of the cost went into the metal. Yanno, the thing that cannot easily be produced in a lab without a particle accelerator), and the clothes, ran us $11-12k (and maybe its because I wasn't always this privileged, but even that much felt absurdly expensive to me). That's even though we're quite privileged and could have easily spent 10-20x time if we wanted.
We just choose not to. People around us were pissed. Whatever.
