You need some of the fashion experts, Paula is very good at fashion, but this suggests 1890's.
The mid 1890s introduced leg o'mutton sleeves, which grew in size each year until they disappeared in about 1896. During the same period of the mid '90s, skirts took on an A-line silhouette that was almost bell-like. The late 1890s returned to the tighter sleeves often with small puffs or ruffles capping the shoulder but fitted to the wrist. Skirts took on a trumpet shape, fitting more closely over the hip and flaring just above the knee. Corsets in the 1890s helped define the hourglass figure as immortalized by artist Charles Dana Gibson. In the very late 1890s the corset elongated, giving the women a slight S-curve silhouette that would be popular well into the Edwardian era.
