I had the old Spiegel 1961 catalog out this morning and looked in the index for "jeans". What amazes me about this old book is what it does not have for sale that is out there for us now. Here is the lone pair of jeans for misses. Looks like more tailored, dressier pants were in order for leisure time and that jeans were for serious work. I can remember wearing jeans but only around home.
I would say these probably would be called "mom jeans" today, don't you think? The price is right for sure. (Click to enlarge)
