I have been trying to find information as to what kind of dress code to have for our rehearsal dinner on the 13th of March. It will be in the evening at Spaghetti Works in downtown Omaha. We're getting married at the Paxton Ballroom in downtown, so decided to do the dinner there immediately following the rehearsal. I don't want to be too dressed up, but don't want a casual rehearsal either. I have a pretty knee-length one shoulder cocktail dress I was thinking about wearing, but don't want to be over-dressed. What do you all out there think?
