I think the unusual thing in the photo is the one long blouse sleeve rolled up. I suggest the woman is very used to having her sleeves rolled up when she works.
Most of the visible hands are strong, capable looking. They are not dainty hands, and the women may not own fine gloves to wear for a photo shoot where they appear wearing their Sunday best clothes. So the hands, or some of them, may be hidden from view.
In the past, having a photo taken was an event worth dressing up for. It's unfortunate we don't have photos of people toiling and wearing their everyday clothes.
