I have a fit and flare gown and it never occurred to me to get a petticoat for it. The bottom has a good flare to it, but it doesn't keep that shape when I move in it. Did you wear a petticoat with your dress. If so, where did you get it? I want some opinions because I have already spent money on a slip dress ($80) that I wouldn't be able to wear comfortably with a petticoat.
