Yes, had to dress up but pantyhose (or tights as most brits call em) was not an issue, just as long as the skirt was the correct length. When I was little I hated wearing skirts, I had ecezma on the back of my knees and all the skirts and dresses used to irritate it.
I remember getting annoyed when I started work at not being able to wear trouser suits to meetings or fieldservice, I often have to work late and if I forgot it was a meeting night I had to go home and put a skirt on. I mean, the suits are tailored for women, just like the jews all wore long robes and it must have just been the cut that differentiated between womenswear and menswear, the cut of a womans suit is different to a mans.
But I never felt brave enough to raise that argument.
