What should I wear for this occasion?

So, my fiance and I have decided to go to the magistrate and get married next friday, we were planning a bigger wedding and decided it wasn't worth it. It's going to be something very low key, a few family members at the ceremony. Later friday we're going to head out to a nice dinner with a few friends, the next day do dinner with family. What should I wear to something along this lines. I've looked for a simple short white dress, I can't find anything I like. I'm open to anything. I'm a curvier girl and have a 36d chest so nothing too low cut, and no long dresses as I'm short and I don't think they look right one me.
