Vera Wang Gown

I am desperately seeking a Vera Wang gown(strapless ivory with a ballgown skirt). It has a split train with layers of accordian pleats down the back(similar to the Romona Keveza dress that is in all of her adds). It also has a simple band of ivory beading around the chest and a flat grosgrain bow at the back. If anyone has this dress new or used(or knows where I could find it) Please email me-Thanks for your help!!
