I have long thought about making a gown like this and since the image was so vivid in my mind I thought a pattern would be easier to find.

However, either I'm phrasing the search queries badly, or the pattern I'm looking for is rare/doesn't exist for sale online.

Does anyone know of a gown (frock?) pattern, similar to this in overal shape and poofiness? Or of a historical book where similar gowns are described? Or is it time to start self-drafting? It is for a cosplay, so it doesn't have to be historically accurate, but I thought this shape was perfect for the character.
