From a Google search. This is probably posted to Pinterest, but I could not find the location of the Pinterest post.
I have seen this dated to the 1820s and 1840s, but the coiffure is 1840s. She wears a sheer wrap plus a heavy one with lapels. The puffed sleeves say early, very early, 1840s or earlier.
