WANTED Desperately - Maggie Sottero Royal Rom

This is my last desperate plea for a Maggie Sottero Royal Romance dress. I am absolutely in love with this dress, but I need to make a desicion soon, and I will have to go with an off the rack sample if I cannot find this one.

Here is all of the pertinent info:

Colors: Diamond White or Ivory
Sizes: 4, 6, 8, or 10
Will take: New, Used, Replica (if exact)
Budget: Around $500

If anyone knows of anything. Anything at all, please let me know.

Thanks everyone!!
