For all those brides who did photos before the ceremony, I'm wondering how you were able to keep your dresses clean? We're planning on doing our pics pre-ceremony, but I'm worried that the train and hem will get dirty and when it comes time for walking down the aisle, it won't look nice and white. What did you do to prevent from getting dirty and for anyone who did get their dress dirty, how did you fix this before the ceremony? TIA
