Okay, so I heard that there are no jean skirts allowed for professional...but, my mom's a partner in a software company. I asked her what she thought, and she said it was fine. It is ankle length, A line skirt. It doesn't have holes or anything, and it looks really nice. So, is it absolutely no denim skirts? Or is it a general guideline..

Absolutely no denim skirts unless you're in a casual outfit
