I found that pant suits are acceptable and never went back to skirts.
I would never wear another skirt. You have to worry about runs. In a professional setting, it's never ok to go bare. It's more trendy but not professional.
You can't beat a well fitting beatiful trouser suit. I have two by William Hunt that I adore and who could ever forget Bianca Jagger in her YSL suit......smokin'.....
