Trust your florist, but your bouquet should complement your wedding dress and formality of your wedding.
If you’re wearing a ball gown with a full skirt your bouquet should be bigger in size than if you are getting married in a sheath on the beach.
To get a fuller bouquet, and save some money, opt for bigger blooms such as peonies and opened roses. Smaller flowers that are considered “bridal blooms” -- stephanotis, lily of the valley -- are lovely but you need a lot of them make a substantial bouquet.
