I am bemused by these illustrations. The style of skirt seems a transition from the excesses of pannier skirts to... well, they did not know how soon corsets and petticoats would be making a (brief) exit entirely from fashionable ladies' closets (in the early 19th century).
And the fantasy that a well dress lady would be out harvesting grapes (or fishing!) in one of these heavy gowns.
Anyway... I love the deep colors in these illustrations. And the different poses should give you good options for using them in a collage.
As I mentioned on the Georgian Fashion Collage Sheet page, I am fond of the military/riding coat look of the redingote (in upper right corner).
