Final choices

Since the dresses are claret (beautiful color by the way) and it is a spring wedding why not use lighter roses to show contrast and incorporate a spring feel. How about pink roses in all different shades of pink and a few ivory ones mixed in. I love the way dark and light pink tones go together. Or, all ivory roses, I am a ****er for all ivory rose bouquets. The contrast of you in your dress with your red bouquet and them in red dresses with all ivory/whitish flowes would be lovely.
Since your bouquet is red and the BM dresses are reddish as well, I think it would be best to avoid red in the BM bouquets, it may not really stand out.
If I come across any pics, I will definitley post.

I agree with the suggestion to avoid red on red for the BM flowers. They either blend into the dress or clash a bit. I like the idea of multiple shades of pink/cream. I'm not sure if this is helpful, but here is a photo of my BM bouquet in a bordeaux dress...

I agree with EvenEdan. I like the all different pinks. I went to a wedding once where the girls had red dresses and all red roses too and it was too much you could hardly see the flowers
