Help! Want This (possibly) Romona Keveza Dre

Found this dress on ebay and can`t get it out of my head. Not sure if it is a Ramona Keveza (or not), but loved the simplicity of the front and interesting qualities (bustle) of the back. If anyone has a dress like this and would like to sell it please contact me with asking price etc - I am taking the big walk on July 2! ... I am a size US size 5/6 - and am about 5`6!

Thanks so much-
Shirer
