How to remove water stain from silk/satin dress?

I got a little bit of water on my dress from Saks Fifth Avenue for my eighth grade graduation...pictures are on Wednesday. It is either silk or satin(I did not get a chance to read the label, I had to hang it up in an enclosed bag). Do I send it to the dry cleaners or are there any home remedies that would work?|||Once silk is water spotted, the only remedy is dry cleaning.
