1857-1865 Baronne de Farincourt by Sergei Lvovich Levitsky (Musée d'Orsay - Paris France)
The given range of dates is "1857-1865." Day dresses had waist bands and natural waistlines early in the crinoline era. The cluster of dated Silvy images have varying pagoda and full sleeves. But, as an average, pagoda sleeves started shrinking in 1863 so this image is dated more towards 1865.
