I have never liked big white weddings and by the time I was 8 I had decided that they emphatically were not for me. They have always seemed to me to be an incredible waste of money.
We married in 1968, 20 guests, a decent meal and the honeymoon delayed until the summer when we could have a beach holiday somewhere hot and sunny. My dress cost £5 from a little boutique on a local high street
Nothing has changed my mind since. DD decided not to marry at all, or live with anyone or have children.
DS & DDiL married first and had children later and had a lovely 'alternative' style low key wedding, with friends giving aspects of the wedding as presents, photography, catering, setting up and decorating the venue were gifts or a communal effort. The whole thing, including dress cost £5,000, which even in 2003 was not much.
My experience has been that the bigger and more expensive the wedding the shorter the marriage. For most of those I know whose marriages have lasted, the marriage was more important to them than the wedding, which were varied but low key and not expensive.
