Feminism in the 1960's

In the early 1960's the pill was available for women and it signified the ultimate feminist expression. To celebrate, women wore mini-skirts and tights, so as to flaunt their legs and parade their sexuality.

Tights became a symbol of female empowerment and independence. Yet, in The Queen's Gambit, the feminist heroine doesn't even wear hosiery until the final episode. I found this incongruent with the era.
