Looking For "BONNY" Wedding Dress

My friend is looking for a "Bonny" dress but it seems hard to find. Its white, very plain and simple has a little bit of beads on the front (bust) and has 2 pieces of light blue material coming down from the back all the way down the train and then connects to the train @ the bottom. I think she`s needing a size 22/24. If anybody can give me some info. On this as to where to find or if someone has one that would be great. Thanks!!!
