I was 17 at the time. My friends and I all thought it was great in that we all wanted to be a princess too. We were from working class or middle class families and were all headed for university or careers rather than jobs just to pay the bills. Nothing wrong with jobs to pay the bills - I now know that's what we all do but I mean it still wasn't essential to go to university to follow some careers then as it is now.
That's the good thing about being young - you can hold two or more contradictory thoughts in your head. We certainly didn't think it was odd that Diana wanted to settle down at barely 20. Quite a few schoolfriends married at that sort of age. They were from comfortable middle class backgrounds and had SAHMs even in their teens. If anyone remembers the 1980s sitcom Butterflies with Wendy Craig as the restless wife in a big suburban house married to a dentist - that was normal for many of my friends' parents and I assume that was was worked for them. Maybe it didn't but lots of marriages don't work out.
We didn't think Charles was old - well we did, but it was more that he wasn't very attractive and seemed old and we couldn't see what Diana saw in him apart from that he was going to be King. I remember thinking that's not what I would have wanted but not that Diana was wrong or her family was wrong to encourage her - those teenage contradictory and compatible thoughts again.
My mum and my older sister and I were very excited about it and my mum and sister are not what anyone would call stupid women. I am certain that if I or my sister were about to do the same thing - marry someone unsuitable rather than marry young - my mum and dad would have done their best to put us off but would have not have stood in our way. After all, early marriages can work and I can see that in some friends and also my family. But we didn't object because it wasn't happening to us and it was someone else's fairytale that we could enjoy.
I remember my dad saying Diana was a brood mare and us telling him to stop spoiling it so he said no more. My dad was often proved right and I'm sure he noted that one but was far too nice to say. Dad, I never said but you were right.
In the run up to the wedding we were on the train home from school and discussing whether Charles was a virgin too. We decided he was. I remember a woman catching my eye and laughing - not unkindly. She was probably about 35 so like really old. I didn't know what she was laughing at and was affronted at her eavesdropping on our shouted conversation on a packed train. What a cheek!
I married at 28 and my husband was 32. I was older than Diana and not a virgin and though I've never asked I doubt my husband was either. He was and still is better looking and in the words of my dad, more "with it" than Charles was or ever could be. My brother is the same age as Charles and he's also more "with it" without being ridiculous now or at any time in the past.
But Diana and Charles's marriage was not seen as weird by people I knew or either by my husband and his friends who I didn't know and were rather different to me. They had all moved to London from various bits of the country to do entry-level jobs in fashion/showbiz/PR and were living in rented flats in Kensington, Chelsea and one in Earls Court a few streets away from Diana's own bachelor-girl flat. Young people could also do that then though their flats were grottier than Diana's.
Mr Limited tells me he and his mates went out till late on the Friday before the wedding - it was The Embassy in Kensington where a pre-Kajagoogoo Limahl danced in a tutu on the bar, bagged a decent spot at dawn in The Mall for a few hours' sleep and then carried on celebrating after seeing the happy couple.
With hindsight Charles and Diana's wedding was obviously not ideal but it's not as if people are any different now. I'm not a fan of Harry and Meghan but I don't understand why so many people are getting up in the air about them.
