Honestly as not only a bride/divorcee myself but also someone who's worked in the industry
Don't get into debt for it - NO wedding is worth this. It is perfectly possible to have a beautiful, meaningful wedding without spending loads. Many items are really frippery - favours in particular! Have them if you wish but they're usually a waste of money. Be guided by the professionals in terms of avoiding unnecessary expense by eg being set on daffodils in September or strawberries in January! They know their products, seasons and prices.
However - I'd recommend not skimping on photographer - the photos can last longer than the marriage! 😂 but also are cherished and meaningful to others too. You want good quality photos BUT you also want a photographer that's good with people, that helps you get the best photos.
Prioritise the people who mean the most to you - not necessarily the most awkward/demanding people, but the ones who you would feel hurt if they feel hurt.
Don't be swayed about any aspect you're unsure of - from the dress to the font on the stationery. If it doesn't feel right trust your gut or on the day you'll likely hate your decision.
When choosing bridal party bear in mind who is most useful in a crisis!
Bridesmaids and best men aren't just ceremonial positions, these are the people who you will need to calmly help when the cars are late, or drunk uncle bob starts yelling profanities during the speeches! I had my sister and 2 cousins, partly due to pressure from mum as my sister and I have never been close. She's also a bloody drama queen! When I needed help because the zip on my dress played up she tried to force it in a panic! Nicked me and I bled on the dress and then started flapping that the dress was ruined when I couldn't see how bad it was! Last thing I needed! Cousin shoved her out the room, cleaned the dress by getting me to spit on a hanky (this works by the way, works best when it's same persons blood/spit), used a pencil to sort the zip and got me dressed and calmed down.
At various other weddings I've witnessed bridal party "personnel" having to deal with all sorts from "tired and emotional" guests to the non appearance of the cake!
You need people who are quick thinking, practical, no nonsense and calm.
On that note accept that it's likely something will "go wrong"
It's usually something minor (place cards swapped or not enough orders of service type thing) but sometimes it will be something more worrying.
Ultimately that you and your partner marry is the only thing that really matters.
And the stuff that goes wrong may seem stressful at the time but will become something you'll look back on with amusement.
In my case a wee cousin piped up RIGHT at the "does anyone know of any lawful impediment" part with a small shout of "me now!" We still don't know why!
Hope you have a lovely day
