This photo shows what some call an “transition era” dress. It has the dropped shoulder seams of the 1860s, but the apron and drape of the 1870s. It’s an excellent example of the transition away from the cage (hoop skirt) and toward the bustle. The photo mount has rounded corners, putting it in the 1870s, but it could be within the first couple years of that decade. You will note the trims added to the sleeve, as well as the ringed apron. Very nice dress.
The photographer of the image was H. G. Pearce, No 87 Westminster Street, Providence – I assume Rhode Island.
