Talk to your local cleaner, or the gown manufacturer about how to spot clean your gown in the event of a spill. Sometimes you can reduce the appearance of a spot by blotting, not rubbing, the fabric. There are spot remover pads that work well on many fabrics, but you want to be certain that you won't cause more harm by not leaving the stain to a professional to deal with later on. Wine or champagne spills should be treated immediately, or stains may become permanent. Place a towel under the fabric and blot the top with a damp cloth wrung out in a solution of white vinegar or detergent and water.
Blot dry to prevent a ring.
