Being sentimentally symbolic myself, I too love how many royal brides make an effort to incorporate this into their bouquets. Then again, I'm a flower-lover as well, so that probably adds to my interest.
Meanwhile I absolutely loved the (IMO perfection) of CP Letizia & CP Mary's bouquets for the symbolism AND how well they went with the gowns.
I really like Mette-Marit's bouquet & dress as well. Not saying that it was for "me" per se, but it worked magically for her and again, loving flowers the way I do, I think I "understood" what she was trying to do.
I also agree that while exquisite & lovely, Kate's bouquet could have been bigger, it kind of made me think maybe she had "left" some back in the car or some pieces had fallen off, and that Marie-Chantal's bouquet, while lovely seemed out of place a bit with the heavy dress & veil.
I also though Martha Louise's bouquet was spot on with her wedding ensemble because the flowers were pretty & complimented the style, although I would have had it just a tad bit longer or bigger to emphasize the lovely heart-shape even more.
CP Mathilde had a nice full bouquet, but....idk
CP Maxima looked so regal, but to me the bouquet had a little too much green
Although I wouldn't carry it myself, Princess Marilene had a nice "country feel" bouquet
