Many Brides coming to the appointment think they need to have the flowers already figured out, they apologize for not being prepared.  Personally, I like going through the design books and discovering the subtle nuances of the Bride's personality.  A few will start off with a picture that they sort of like or they believe will be an inexpensive design.  As we go through the process of designing the bouquet the Bride becomes more confident that her Wedding is reflecting her personal style.   Never feel that your style is silly or immature......I rather work with a Bride who likes to add lots of personality to the wedding day.
