It's good to know my husband isn't the only picky man out there! You know I went through almost 10 bridesmaid dresses before we could agree!

What if you both compromised (good practice for marriage)? What if you did your bouquet just as you want it (and do keep in mind the overall size can be overwhelming if you are petite - pictures will be the dead giveaway) and do what he wants with all the bridesmaids bouquets. A little yellow never hurt anyone. If you really aren't that set on yellow, than I think it's probably good to just throw that one out - there are SO many colors to choose from.

It's great that he has opinions, but to reduce stress, it's good to communicate before and know what each other's expectations are from the start. Guys do tend to feel left out if we assume they don't care.
Good luck!
