I remember those!!! I also remember my aunts bending over to lock them to the single hose they wore, one on each leg, and screaming when their fingernails started a run in those extremely hard to get hose!!!!! They were precious things, and I would be sent to "the store" to see if one of my Grandma's kin would have a pair or two of them "below the counter" for my aunts. I'd get them in a paper sack so no one could see what they were....they were THAT precious and hard to get.
