Sorry this is long.
I think my Mom would have killed me if we eloped. We did consider it. The wedding started out small and got large, but, large on a budget. We were engaged for two years so we had plenty of time to plan. The first thing I did, pre-Amazon days, was to go to the book store and find a few books about budgeting weddings. We had the wedding at mid-day. This meant we could feed people lighter than at supper time.
We had two hundred people at a local hall. We got married and had the reception in the same place. The hall allowed us to bring our own food in and there was a cash bar. I made the menu from foods easy to find food clubs and restaurant supply stores. I had, (she has since passed away), a friend who was a para-professional caterer. I bought the food, she cooked it and got friends to help her serve it buffet/station style. I stalked the clearance tables of party supply stores for two years, picking up matching dishes, cups, flatware, the guest book, thank you notes and gifts and all kinds of decorations. I used coupons at craft stores and made my own baskets for the bridesmaids and helpers. The bridesmaids jewelery came out of a catalog, clearanced priced. I also made the decorations myself. A few of my friends did the decorating the day of the wedding. I hired a friend to DJ for the reception and take care of the music for the ceremony. My Mom is a photographer. She insisted on doing my pictures and album.
From the first, I made clear to my Mom that my dress would not cost more than my rent at the time. My sister had just got married and spent nearly 3 times my rent for just her dress. A friend altered my dress for me. My Mom had a ball making my headpiece. I got the material, forms, lace, pearls etc. from the fabric store, on sale/clearance. The invitations were ordered by mail and came with free thank you cards. I ordered favor boxes with the invites and filled them with heart-shaped Dove chocolates. I got the chocolates first thing in the am, Feb 15 on clearance. It spent six months in my parents freezer.
I think the only thing we paid full price for was the DH's tux the limos and the cake. My parents bought that for us. They also bought mine and the bridesmaids flowers. I purchased supermarket flowers and made corsages and buttioners myself with floral supplies from the fabric store.
The only thing I didn't have that I wanted was an ice sculpture for the main buffet table. I ended up spending that money in a way that was totally unexpected. I also forgot about the videographer. None of my family brought their camcorders either.
The honeymoon was budget too. I got restaurant GC's and hotel expenses paid for by sitting thru two timeshare presentations.
The whole thing cost about $5000. We had zero debt from it. My Sister, who has had two weddings, and my cousins all had their weddings, catered, in fancier places and paid more. Their pictures look the same as ours.
