Bridesmaids Bouquets

So, my bridesmaids are wearing platinum in the wedding. My other color is crimson and I want to blend it into the ceremony as well. I'm thinking that I want to do something crimson for the bridesmaids bouquets. I like the color of these (to the left), but I don't want their bouquets to look like a round ball of flowers on a stick. I had this bouquet at the last wedding I was part of. It was terrible. I want to do something in this color, with some greenery, but not much else. Sadly, I am flower illiterate. So....I guess I need a bit more help and time here.
