These are late 1970s vintage Levi's Womenswear (one of their fashion labels) and quite rare.

The fit is fairly high-waisted & slim, with straight legs. This pair is tan corduroy, still a bit stiff with  creases. Please see the last pic of the jeans photographed under bright sunlight. Zipper fly with a #42 Talon zipper & copper button & rivets, belt loops,  and the classic 5 pockets. 

These are dead stock, purchased from Bloomingdales. A great pair of jeans with a lot of life to give!
