“Dolly Varden” dress ca. 1870. This style of dress was inspired by the 18th century polonaise. It was named for a character in Charles Dickens’s novel Barnaby Rudge (1841). Photo probably scanned (by the Delsa Espirides blog) from Fashion: A History from the 18th Century to the 20th Century by the Kyoto Costume Institute.
Two-piece day dress, Nice, France, ca. 1870-75. Light green cotton/wool with beige pleated silk trim. Bodice lined with cotton, closes with fabric-covered buttons. Skirt with pleats in back, hem reinforced with cotton and woolen band, closes with hooks & eyes at waist. Mode Museum, Antwerp
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."
