WANTED: Oleg Cassini CT203 Champagne, SZ 18W Or Larger

I`ve seriously increased in the bust area since I bought this dress in a sz 16 in September---it mightbe hard to alter the dress that much, really. So I`m looking for a Oleg CT203 in Champagne, size 18 or larger that I can alter down. My wedding is in mid-October 2009.

Incidentally, if I find one, I`ll have a size 16 CT203 to sell. It`s already been bustled, but otherwise unaltered.

Thanks!
