Yes: When I was working my standard uniform was Dockers and button up or Polo type shirts and a suit when visiting a customer site or representing the company in a business capacity.
My cruise uniform basically turned into work clothes. During the day I wore basically what I would wear at home; shorts, t-shirts, tennis shoes.
It was nice, in a way, that I could just grab some "work clothes" and put them in the suitcase and I was ready to go. I still have a rule that there are no "cruise clothes". If I can't or don't feel comfortable wearing it at home then I won't buy it for a cruise.
