Today, I took my dress out of the bag for the first time since my fitting to show my sister. Upon doing so, we found multiple dirty spots! I have no idea how they got there, and all I could do was cry. I didn't trust someone to alter it, and now I have to trust someone to clean it. It seems like it's a dusty kind of dirt (possibly from the dress shop?) and will need to get it dry cleaned. Someone just told me, however, that they worked in a dress shop and that dry cleaning it could make it worse? Never heard that before, but I'm scared now. My dress is satin (Maggie Sottero Monalisa Royale), and I will absolutely die if something happens to it. What do I do?
