Selling Paloma Blanca Wedding Dress 3558

I am selling a Paloma Blanca wedding dress #3558 size 8. I was told when I bought the dress that they could let the dress out a couple of inches. The dress has been hemmed to fit me - I`m approx. 5`4" and I worse small heels. The dress has only been worn once. I notice that there is some dirt at the bottom where the dress was running along the ground. Could dry clean. Selling for $600 OBO
