Oleg Cassini 8CWG635 Monochrome unclassified dresses

I tried the dress on once in the store when I purchased it at David's Bridal.  It has not been worn or tried on since then.  My fiance and I have decided to elope instead, so I'm not going to be wearing the dress after all.  I purchased the david's bridal garment bag for $11 and will include that for free.  The dress is still for sale at David's Bridal for $1499.  I have the Champagne & Ivory colorered dress.  I typically wear a size 18.  The dress is the same as it was on the sales floor when I purchased it. I did not see any defects when I was trying it on.  It has not been dry cleaned.  Please ask if you have any questions.
