My sister does. At least one of them. She says her office is very dressy, and she loves dressing up for work. UGH! is my opinion.I haven't worn them since I was in my 20s. I wear footless tights in winter and bare-legged under my skirts in summer.
I wear ankle length skirts.
No one, where I work, wears them, as far as I can tell. Everyone in the building I work in dresses just as shabbily as I do.
