Man, fashion for ladies was awful back then! They all look so old, despite the fact that several of them would look pretty young and hip with a modern makeover.
I can't tell if you're trolling or not, but I'm guessing they all look old bc we're used to seeing those styles on older women, namely women of that generation as they aged.
Plus, the women in that line are literally herding cats. That'll age anyone.
They aren't wrong though... these women are from a time when there was really only fashion for children and fashion for adults, it was only as the 1960s progressed that you started getting fashion specifically for younger adults.
