I am curious to see what is a no-no where you work, or a must-must.
When my sister worked at JC Penny, pantyhose were required. No open toe or heeled shoes. Pants only when it was below zero. And long sleeves.
At some places, women are required to wear makeup on certain features--mascara and lipstick. Several years ago a flight attendant was in trouble for not wearing mascara on the job.
