Paloma Blanca 4164 Unique unclassified dresses

This designer gown was purchased new from Paloma Blanca in Canada and has been used as a sample gown in a couture bridal salon in San Diego. This gown is in beautiful condition. I bought this gown but ended up falling in love with another gown a week later, so I am trying to sell this one. It is still at the bridal Salon, it never left the salon and it has not been altered at all.  The label size is 10 and I'm not sure what the street size is, but I put down 10 although I know the street and label size differ. If you are intereted in this dress I could call the salon and find out the street size.
