WEDDING DRESS EMERGENCY

So I picked up my dress yesterday, and there is a stain on it from what I’m told is dry cleaning fluid. Meaning she has tried to clean a stain and in turn whitened the fabric too much in that spot. The spot feels different to the rest of the dress and is definitely noticeable - also in a very noticeable spot. She said to get rid of it the whole dress would likely have to be submerged in the dry cleaning fluid, meaning the whole dress would then become a different colour and the feel of the fabric would change. THE WEDDING IS 4 DAYS AWAY. The dress is made from a silk satin chiffon. Do I bother and take it in to the dry cleaners to see if they can fix it? I’m so nervous they’ll just do more damage. I’m so upset. This isn’t the first thing she ruined on my dress while making it.
