Covid seemed to change workplace attire in my company forever. I used to wear a coat and tie to meetings and events.... I'm now wearing a polo shirt and stretchy chinos with "dress shoes" that are basically sneakers.
I've often thought that we can squarely blame Western Europe for the proliferation of suits being the normal business wear. It makes sense for them because have you visited the UK in summer? Or northern the northern half of the continent? It's downright cold sometimes. In the middle of summer. It makes sense for them to wear all that crap all the time. I do wish we weren't influenced so heavily by that to the point that we don't have any real alternatives when it comes to formal and business attire.
