Weddings then varied (as now). Some had 'catered' weddings others were more DIY. My father worked as a hospital chef and did the food for some friends at our church, with friends helping out to serve. Soup, roast (if I remember right) and maybe a pudding or cheese and biscuits. The soup was a choice, tomato or oxtail. Can't really remember details of the other courses.
Couples in the 50s didn't live together before the wedding so were assumed to be in a hurry to leave for the honeymoon.
I remember my cousins wedding, it was a meal in the afternoon for guest (family) and an evening do (disco perhaps) for the 'young people' - the friends of the bride and groom.
I call at ceilidhs, so see a lot of present day wedding dos. I've been to some in church halls where friends have catered / provided flowers / etc. etc. others in expensive venues where every detail had to be correct. And all sorts in between.
In the 50s you'd never have thought of spending out on fancy skirts for chairs! The war and rationing was not that far behind us, money was tight for most. (And we had more sense)
