I think certain flowers have a particular significance for each of us. Finding an inspiration point and blending that idea with your dress is just the beginning of working one or a few colors into an overall theme. Size and proportion are something else to consider. Some of us like the idea of carrying a huge burst of three to four different kinds of flowers in an arrangement while someone else goes for the simplicity of a small nosegay.   Since flowers are a seasonal thing--tulips in spring, mums in the fall, your dress is probably going to reflect that too. The images below are all about Spring pairings, by Santa Barbara-based Camille Panzerello.
