As far as the figure it self goes the skirt I think is a bit too short.
The folds make it look like it's made out of very stiff fabric but it's too thin looking to be stiff.
I think it most likely would have been made out of wool or polyester in the early 70's.
So there would be less folds and what folds there are would be more subtle.
If you look at a kilt there are no folds unless they are added by pleating.
Most skirts just hang stright down unless the folds are sown in by bunching at the top.
