Sad that denim is now considered “dressing up”. The slobs are winning and wearing sweatsuits to business meetings and funerals.
I worked for an insurance company in Vermont back in the late 90's...although a professional office setting; women were allowed to go barefoot. No stockings, knee highs, or socks...barefoot. I could control that somewhat by announcing (best in late afternoon) "Aw, hell...I must have stepped in some dog sh*t while I was out to lunch...I must have tracked it everywhere." Shoes/sandals magically appeared.
Nowadays, here in soviet Red Hampshire; I see women going about their local business (Post Office, the dump, and so forth) wearing pajama bottoms.
