This seems to be the same dress, but in the first picture, there is a pale blue insert on the bodice using (apparently) the same material as the skirt & cuffs. The Costume Gallery of the Pitti Palace in Florence says this is a wedding dress made in Naples between 1876 & 1878 (photo: Marcello Bertoni). The picture on the bottom was taken by a tourist, Joseph Hilsey, for his blog, Material World, and is described as "Yellow and cream striped silk over pale blue underskirt, ca. 1878."
