^^ My boss and I were just talking about how we have changed our dressing styles over the years (I've worked for him for over 25 years).
He used to wear suits, then went to dress pants and nice shirts, then to khakis and polos, then to jeans and tees. I used to wear dresses with heels, then dress pants and blouses with nice shoes, then jeans and tees/sweaters/tanks with boots or flip flops. We both go barefoot sometimes. Not sure how much more casual we can get. hahaha.
