Sure as hell did not happen when I married my wonderful wife.
MIL and FIL had a acrimonious divorce about 10 months before our wedding. FIL,who was a stinking rich GP would not attend his daughters wedding because the MIL,who was *** poor was attending.
FIL gave us about £300 for a honeymoon. MIL subscribed for us some Food recipe cards which ran every month over a few years.Trouble is we only got half the set as she peed her money away and couldn't afford to continue the subscription.
My wife ran up a beautiful wedding dress for herself on a old Singer hand cranked sewing machine. Likwise two Bridesmaid dresses. One for her sister and one for a fellow nurse in her training set.
She baked the three layer fruit cake and my best man knew a copper who previously was a baker so he iced the cake for about a fiver. We provided the nurses hat and copper's helmet as decorations on the top layer. Best man also knew a character who provided a Roller on the day to bring wife and brother (who gave her away) to church and us both onwards to the reception at the Victory Services Club at Marble Arch . I suggested,beforehand. I put £300 behind the bar for guest drinks ( this was 1976). The steward was amazed and assured me the booze prices were the cheapest in Paddington and £150 would be more than enough. He obviously didn't know coppers,doctors and nurses when booze was available with a kitty behind the bar. By the time the photographer had finished with the usual photos of wife,bridesmaids and I on arrival at the reception the kitty had been drunk dryand I was asked to pay for my first pint. :-)
When and if my two boys marry we will definately consult with their in laws and contribute equal expenses for their happy occasion.
I have no regrets that we managed a wonderful wedding on the cheap and so proud how my wife could knock up a great wedding dress and those of our bridesmaids.
