I'm a HUGE Sailor Moon fan (fat pun unintended), so I forced my bridesmaids to wear different colored sashes on their dresses and pose like the Scouts do. The flower girl is there merely to be adorbz.
The couple commissioned a comic artists friend of theirs (at http://www.viruscomix.com/subnormality.html) to create a picture of their wedding party. The wedding photographer then had everyone recreate the pose. I think it was done very well.
