That’s for sure. Try Sacramento heat in the summer - no one appeared at work or anywhere else formal without stockings!! I think ‘60’s was early for pantyhose but we all took advantage of them when they came out. We wore stockings and garter belts..or I guess some wore girdles?
Pantyhose as we know them now seemed to become common in the mid to late 1960s - you needed them with the mini and micro-mini skirts.
Most of us wore some kind of girdle (’foundation’) with garters attached back then. I was happy to get rid of that and use the garter belt.
