ROB, ok, let me settle this. There was no need to mechallel Shabbos for parnossah in Europe (unlike in America). The kosher food was readily available. Not covering the hair did not help alleviate anti-Semitism. Enough of boba mases!
About the skirt length — stop with your fabrications! Who told you that not covering the knee used to be muttar? Again you are not a Talmid Chocham to pasken on it. Plus, see what WIY wrote.
