I have not worn a dress shirt since March. I’ve got them all in plastic wrap. Working from home.
In my neck of the woods, suits are either for very low level or very high level jobs. Everyone else is business casual or even the Steve Jobs route.
I have a friend in the dry cleaning business. Not doing so well, either.
Yes I have noticed too, even before the virus, that “business casual” has become the “dress code” more and more in the business world, and formal business suits are seen less and less.
