I can't seem to find these kinds of dresses as simple as their design is. If i do it's always extremely short like this one. The best descriptor for the dress I'm looking for is having a similar silhouette to the regency era dresses, like in bridgerton, cinching around the underbust and the rest of the dress cascading straight down and ending preferably around the ankles or well below the knee. I'd like to find the black dress pictured or one similar to it
