I'll let the pictures do the talking.
At first I thought I wanted an all green bouquet that would really pop against my white dress. But I do want mine to be different from the girls' and lately I've really wanted to as least be a little "bridal" with white flowers. So currently I'm planning on a mostly white bouquet, with green flowers mixed in.
Now I've got some research to do on white fluffy flowers.
