1880-1910 ? Bicycle Riding? Horseback?

This is the last scan I got out of my scanner before it gave out on me (note the scanning artifact on the left side). Been trying but haven't fixed it yet.

I found this at a yard sale and I don't have any back story to go with it, just thought it interesting because this would have been very uncommon attire for women in those days. They look a little too well dressed for hard labor, anyone have any ideas?
