One of Empress Elisabeth of Austria’s (1837-1898) dresses (c. 1880). This dress is made by one of Sisi’s favorite tailors (as far as I’ve read anyway), Fanni Scheiner. There’s another view of the front of the dress at the website for the museum where the dress is located. You can view it here.
1900s Evening Dress: Followed the same silhouette as daytime, but made of softer lace or sheer fabric at the neckline with ruffled decorative sleeves covering the upper part of the arms, which featured the skirt gowns full detail that either extended to the floor or tailed along the floor.
