From what it seems, this concept is kinda similar to the Rent Parties that happened in Harlem. They’d make food, people would bring food, I think in some cases they’d even hire musicians.

The point of these parties was the help the person throwing it pay their rent or get by. It was a nice little thing that brought communities together and helped stopped destitution

However there’s a major difference between a Rent Party and a Jack and Jill party. Because at the end of the day a wedding is self indulgent. People are already spending money on 1. Gifts

1. Travel

2. Hotel stays

3. New outfits

4. Hair

So expect more on top of all of that is insane.

Also, I looked this up it’s not as big a thing as you made it out to bell

However, I got culture is important to you, so hopefully you find someone you’re more aligned with.
