Hunting For White & Black Wedding Gown

I am looking for what is thought to be a Lady Roi gown...although even after talking the company I can`t prove that it is. We saw this gown in April in Dallas. It has been discontinued... It wasa a size 8 corset top with full tuell skirt. I looks like two piece but is only one piece. This white gown was trimmed in black satin. The Black was on the top of the bodice and up the boning in the corset top. It laced up in the back in black and had 2 or 3 stripes of black on the lower portion of the gown. Even the attached train was trimmed in the black satin. My daughter is just beside herself because it was sold. AND the store doesn`t even have a record they can trace as to who may have bought it. We would gladely pay a resonable finders fee if you can find it and we could buy it. We are rapidly running out of time. Our second choice gown is pretty but not what she has her heart on. She will be putting herself thru school to be a lawyer and will be broke for a long time. I would love to give her the dress of her dreams. PLEASE help if you can. We think it could maybe be as old as a 2003 gown but really don`t know if we even have the right designers. We would gladly buy it in new or used great condition. Thank you, Beverly AKA mother of the bride.
