OP said: "1860's Sheer Dress, appears to be from Simplicity pattern. Really pretty green vertical stripe." I think this is an original; the "time travelers" watermark is from a well-known Ebay seller of original garments.
Evening/Afternoon Ensemble, With Evening Bodice, Texier St. Engley: ca. 1875, French, silk. "An air of coquettishness and youthful presence inform this set of French dress coordinates. The colorful and spritely decorative details lend a sense of whimsy. The choice of fabric and the inclusion of alternate bodices made this ensemble appropriate for both late day and evening wear."
