Anyway. Beginning in the 1840's, the large sleeves from the 1830's were replaced with tight-fighting sleeves. Remember, by now the waistlines had gone all the way down to the natural waist. In this age and era, no one knows where their real waist is. It is a bit ridiculous, actually. Your waist, ladies, is right at your last rib. It is not on your hip bones, where your pants come up to. It should be the smallest place around.
Another thing that was a part of the 1840's was smocked bodices, like the one below. I don't know if I have ever seen a smocked bodice in the 1850's, but the museum says the one below is from 1850. Go figure. 1850's was similar to the 1860's, in that tight bodices like the one above and the last one, with gathered bodices for work dresses.
