Ugh. And the sexism starts.... Men have families and friends they want to invite. My husband invited about twice the number of people to our wedding than I did.
Some people have absolutely no idea of the cost of things. You're buying dinner for 200 people for a start. How much do you think that costs?
Say you take your family out to a slap up dinner to celebrate something... i dunno, a birthday, an anniversary, some achievement , maybe you won an award. How much do you think that costs? Both sides of your family... mums , dads, siblings and partners. Maybe a couple of aunts or neighbours. Include wine. Let's say 40 people. How much would that cost you? You won't get much change from 4k. Now, maybe you want to add a suit and a nice shirt to that, you nip down the tailors... 500 quid? A new dress, hair, shoes another 500. You're at 5k here already for a dinner out with a small group.
Now, multiply that up by 5 (include suits and dresses for other bridal party members) to get to your 200 people. Look here, you're at 20k on just dinner, drinks and some outfits. None of that is frills.
Think then of everything else that gets added. A wedding cake, wouldn't be outrageous to have one of those would it? Entertainment for hours, maybe music in the ceremony, and music after your dinner? The ceremony itself and registrars, they're not free. A photographer.
All these things are thousands more, and none of this is yet a blingy wedding.
Put yourself, your parents and the bridal party up in the hotel for the night? Another 2k.
Now, you can of course go to the registry office, and then out for a bag of crisps and a pint after. That's fun too, and some couples do it. But if you want to buy dinner for 200 people, you're into big bucks straight away. And you cannot persuade me that every fella in the universe wants the crisps option, and every woman wants to treat her friends.
