@Aria My brother got married last year and had a pretty good way to avoid it costing a fortune.
He got married in a field.
A field owned by a friend of my sister in law's family, the seating for the ceremony? Made by him and his friends out of scrap wood the day before in an isle of trees at the edge of the field. They did rent a tent along with paying people to run a hog roast and an icecream stand but the whole thing cost a couple of thousand (pounds sterling) whilst being an amazing day.
Especially memorable was every bridesmaid either leading or carrying a happy dog.
