We had a 120 person guest list, open bar, DJ and favors, and spent about $4000. Our big savings were -
Silk Flowers - seriously, way cheaper, and they have beautiful flowers for cheap. We used them for center pieces, our cake topper, garland, whatever. Everything looked very classy
Dress - I got a $1,500 dress for $400 because it was “last season”
Make your own stuff - not everything that’s handmade looks like third grade. I did centerpieces, tulle and light garlands, the cake topper, the card box and various things all by hand, and it looked elegant and professional. Talk to relatives and friends, and see if they would be willing to help out in lieu of a gift.
Miscellany - lots of things can be replaced from a big budget wedding by being creative. Instead of spending $50+ on a guest book and feather pen, we did a $20 tablecloth and Sharpies for everyone to sign - it was great, since it gave them room for well wishes and stuff. Instead of a silver plated cake set, we went with the $12 version from Hobby Lobby. Instead of buying table number holders, I used a stack of silver car stock, printed names, and used a $3 corner punch to make them pretty.
The only thing we didn’t cut corners on was food (family style saved us one money there, but the food was delicious) the bar, and the favors - we did tiny bottles of Korbel at each plate with a ribbon on the neck, although I suppose that saved me on bar fees for the toast and serving glasses. It was important to us to not skimp on the guest stuff as opposed to the pretties for us md the room.
I had a beautiful and elegant wedding, on a Saturday evening. It was great. It can be done - most wedding guides are sincere bullshit.
