Perhaps my belief that it was best not to "go crazy" with wedding expenses stems from a story my mother told repeatedly over the years. It concerned a family (sort of) wedding that took place around 1960, before I was even born. Apparently, the wedding....well, mainly its fallout.....made such an impact on everyone that it served as the cautionary tale of the century.
A niece of our uncle (he was married to our aunt) was getting married to a young man who came from a well-to-do family from another state. Long story short, he had more money than her family and her family was determined to put on a wedding that was up to snuff for his side. Problem was, they simply didn't have as much money. Period. Worse yet, it seems they had some inflated idea of what kind of money his family had.

They were not old money....The parents were immigrants who had come over with precious little but had worked hard and succeeded in business. Truly, they respected anyone who worked hard. Not snobby at all, but her family didn't know that and just HAD to put on the dog.
Soooooo.....The bride's family which had a paid off home and a decent income, but was not wealthy by any stretch of the imagination, went wild with the wedding. My mother shook her head for decades about how they spent
$1500 on her dress back in 1960. Seriously, do you know how few dresses cost $1500 back in 1960, especially in Texas? I don't know if Lyndon Johnson's girls wore $1500 wedding dresses.

That was just ONE of their expenses.
Before long, they had to take out a mortgage on that paid off home in order to afford the wedding. Big mistake. Not long after the big day, the daddy lost his job and eventually, they lost their house. A house that had been 100% paid off and totally theirs.

All for a super shindig meant to impress the in-laws who truly did not need to be impressed.
The postscript is that the newlyweds were still in college and had assumed that wealthy father-in-law would continue to support the son (groom) as he continued college. Pay for housing, utilities, tuition, etc. Never assume. When they said something to him about it, they found out he was old school. He said, "Uh no.....You're old enough to marry her....You're old enough to support her." Major mistakes made on both sides, it seems.
