My wedding probably cost 1500-2000 back in 1990.
My grandmother bought my dress, shoes, etc. (dress was $99 on a clearance rack, and it was perfect for me). I couldn't find a veil I liked, so I made one myself -- very simple and inexpensive.
My mother took care of the cake and food at the reception (punch, cake, heavy horderves type thing) and decorations.
I paid for materials for the six bridesmaids' dresses and my mother made them (total cost about $200).
I paid for the invitations and flowers.
I don't remember who paid for the photographer.
No DJ, no alcohol, no limo.
My father-in-law paid for a nice rehearsal dinner at a casual restaurant.
My husband paid the pastor, he paid for our rings, and he made the downpayment on a house (bought the house instead of going on a honeymoon).
If I had it to do again today, I'd do something very similar. Those of us in the South consider this a nice, average wedding -- the great majority of weddings I've attended have been this type of wedding -- we don't traditionally "do" sit-down dinners, nor do we tend to go into debt for wedding celebrations. One of my Northern relatives, however, was crass enough to walk out saying that my wedding was "boring" because we didn't have dancing. Wonder why my sister didn't invite them to her wedding a few years later?
