Someone Please Help!!!!

I`m getting marreid next yeah and have been looking at the maggie sottero collection and have fallen in love with the Rayna dress. But i have yet to be able to find a store or website that had heard of this dress appart from one which just sold their last one. Please can someone aide me with finding this beautiful dress. Apparently they stopped making it in april so its just a matter of finding someone that still has one! the website i found the dress on was http://www.theweddingwarehouse.com/
Perhaps someone might reconise it. Any info would be much appreciated.
