I love it!
The only thing I can think of is my knee jerk reaction to them not being a "fad". I'm not extremely knowledgeable of wedding practices and what not, and prior to you, I'd never heard of a brooch bouquet for a wedding. I have to assume that some of your viewers haven't either. When I read that they are not a "fad", it implied to me that there are a lot of other sellers creating these and selling them right now (and there may be, but hopefully the reader is interested in YOURS). Other than being absolutely gorgeous, I also liked them because they are unique and one of a kind and I'd never seen them before. The fad reference did the opposite of what it was probably intended to do, and cheapened the over all feel for me.
It's nit picky and I doubt a lot of people will have that reaction, but that was my personal reaction. In truth, it was a very fleeting feeling, until I stopped to think about how I could explain it. Had I just read it without planning any feedback, I probably would have just kept on going mostly unbothered. I feel like I did a really poor job explaining it, haha, but hopefully it makes some sense!
Other than that one word, I love it! I never planned on having a ceremony, but after seeing these, I want one now. Haha
