Re: Flowers.
I had the full whack: a bridal bouquet, 2 bridesmaids, 2 flowergirls, 8 buttonholes, 2 corsages, 10 table tops and a large arrangement for the newel post on the stairs. These were done by a florist.
In the church, we had one long arrangement in the vestry (which was transferred to the top table in the reception) and one large arrangement at the front. These were done by the “church ladies”, with flowers supplied at wholesale prices by our florist. My flowers were cream roses and orange Calla lillies and the cost for all of this was £500 (about $750), of which £100 was my bouquet, considering what we got with our money I think it was pretty good value.
Obviously, you could do it for much less.
Shop around for a nice florist for your bouquets and talk about getting seasonal flowers which will cost less. If you’re not particularly fussy about the type of flower and more about the colour, you could give your florist the freedom to pick the cheapest flowers in the right colour that are available at the time (wholesale flower prices fluctuate depending on weather, demand and availability) obviously that is going to be easier with white flowers and harder with purple ones!
If you can find a florist who will do your bouquets, and get you flowers for the tables at wholesale prices you might be able to do the tables yourself the night before the wedding and save money that way. If you have friends who are good at flower arranging, they might be willing to help too.
Greenery is cheap, flowers are expensive, so you could use less flowers and more greenery to save money. Candles and/or confetti on tables is also a cheaper alternative but will look really festive.
Single blooms instead of bouquets look very modern, so perhaps you could think about carrying a singly lily, rose or peony, or if your daughters would prefer not to carry bouquets at all.
Good luck!
