So I bought from dress from Running of the Brides and my seamstress gave me a fabric bag and sheets and said I should clean it before she alters it. She recommended a dry cleaning service and they said they would have to see the dress but cleaning runs from $130 and up.Another place said they would have to see the dress to estimate the price. I don't want to preserve it, just clean it.My dress isn't very big. It's Bienal by San Patrick.What did people do to clean their dress? And did you do it before or after alterations?
