I dont work at weddings, but is a given that the more expensive the wedding is, the shorter the marriage might be.
A big huge expensive wedding is a outbox stress, a vanity display and usually the bride is one of those who want the dream perfect wedding they wanted since she was a child.
Then comes the hyper fixation with aesthetics, that might translate into controlling and micro managing everyone on the wedding party and pushing people away for not matching it.
In the end, nothing about the wedding is about the love, being together, etc. It is just a huge waste of money just for some perfectly curated pictures. The marriage itself is no longer relevant and the couple might not last more than 2 years. Just keep it simple people, or even better, just elope.
