Small arrangements placed on tables for a seated meal. Other options include a small arrangement on the guest book table, and floral decorations on the cake table. Consider the style of your dress and the formality of the occasion. Talk with your florist. Many professional florists have photos for you to view to help you with the selection of your boquet.
Many brides use part of their bridal bouquet for their going away corsage.
It saves on expenses, and is one less floral arrangement to keep track of. Usually a smaller version of the bride's bouquet, perhaps with a slight variation. The bride can suggest just about anything to the florist. We were married in December and the bridesmaids had hand muffs made to match their dresses with floral sprays attached. Paid for by the bride's parents.
