I do not own Cécile, but here is my #26 modeling the bonnet, dress and boots. I will admit I bought it because of the bonnet and I do love the bonnet. The bonnet is made of a soft and flexible straw looking material. Addy's bonnet is very stiff compared to Cécile's.
The dress as others have expressed is thin and cheap. I would have preferred it be made out of a material that didn't remind me of a child's play parachute. I would have liked a nice breathable cotton material. I do not know anything about material used in the 1850s, but Cécile would have sweat like a pig in this dress in the New Orleans summer heat. Dollies do not need swamp butt.
Overall, I like the style and color, but the thin material is quite discouraging for a price tag of $36.
