The size of your wedding, as in the number of guests and the size of your bridal party, will affect how you order your arrangements and how many you order. The number of people that will be attending the reception will determine the number of tables that you will need to outfit with centerpieces and consequently this will impact the overall cost. However, if you are having fewer centerpieces than the average wedding requires, you may be able to have the more expensive flowers you have always dreamed about so prioritize your decisions based on what will make you the happiest.
In addition to the reception, you also need to take into account the number of people in your wedding party: the bridesmaids, groomsmen and flower girls. These individuals will also need to be outfitted with different kinds of flower arrangements, such as bouquets and boutonnieres, so when the groom complains about the costs of the flowers, remind him that the number of guests and the size of the wedding party have a dramatic impact on the overall cost of the wedding.
