1870s (?) Countess Castiglione wearing dress with two skirt panels by Pierre Louis Pierson
From servatius.blogspot.com/2012/05/countess-of-castiglione-c1870.
I doubt this photograph was taken around 1870 based on the dome crinoline she wears and the pagoda sleeves that are reduced to a revival of hanging sleeves.
