how much does it cost to dry clean a prom dress?
Average is about $25.00, for a good, quality dry cleaner. 2. If this is the zipper for the prom dress, it would run about $12-$20 or so, depending upon the fabric, the seamstress labor, and the quality of the zipper (plastic vs metal, etc) 3. I don't know what to tell you about the alterations to make the dress bigger without seeing it firsthand.
