Here are some before pictures of a wedding gown we cleaned from a bride who was married on a beach. She was able to keep most of the gown pretty clean, except for the bottom. The sand and dirt managed their way into all of the layers of the dress. The middle layer was somewhat protected by the other two layers (Scroll down to see the after pictures).
Here you can see how the dress turned out after our unique cleaning process. This wedding gown is going to be preserved but I took a couple of pictures while we were waiting for the bride to come and view it before we pack it into the preservation chest.
