Go to the part where Marguerite and the baroness are looking through Marguerite's dresses. Jaqueline comes in complaining that her dress is to small. The dress is twisted foward with the laces undone. The three then go to the other room where the baroness pulls out Danielle's dowry dress. They show Jaqueline again. This time her dress looks tailor-made. If you were watching closely, you'll see that it's the same exact dress that was too small a few minutes ago.
