This really varies a lot. I don’t remember exactly how much we spent. We paid for a lot of things ourselves, but my parents paid for the actual reception/lunch. My dress was only a couple hundred dollars, and was very nice. The church was already decorated, but we did spend some money on mine and the bridesmaids’ bouquets, etc. Our photographer was actually one of the biggest expenses, but it was one of those things that was important to me so we spent (I think) about $700. We have some great pictures.
There are definitely ways to keep costs low, but it depends on what you want. Some of the little things can add up really quickly. The church fees, flowers, dress, rings, tux rental, cake, honeymoon…most of it can be as cheap or as expensive as you want it to or can afford.
One thing I would recommend being on the same page about from the start is how many people you want to invite. The list has a way of growing, and if you set limits at the beginning it will help to have an agreement. Depending on how much $$ per plate you are spending if you are at an actual wedding venue, it can get expensive really quickly. Ours was a fairly smallish (around 50 people) wedding, which is what we wanted, and our venue and budget could not accommodate everyone bringing dates, etc. People might complain, so be prepared for that. If you have an unlimited budget and space it’s not a problem, but if you do have to set limits some guests can get rude. It’s good practice for the future, when you have to learn early how to say “This is what we have decided.”
