Working at an uni hospital, as researcher, there's not really anyone who tells you what to wear.
Besides security measures, which is the only thing which prevents everyone coming with shorts and sandals.
Normally only the professors come in a buttoned shirt, and only the head of the department in some sort of suit, but that's it roughly.
Therefore, I've used my suit exactly 3 times: Once on a wedding, twice during ceremonial duties at a PhD defense. I'll wear it in the close future once more for my own, but then it'll probably not come out of the closet for quite some time.
For presentations at conferences dressing up a bit is probably warranted, but in a real suite would probably look a bit out of place. I might dress a bit better when I have to give a lecture to students later this year, but haven't really decided.
I normally also dress a bit better when I go to big parties. Because the other gender, but my effort there is rather minimal.
Shirt and tie (but not the suit jacket).
I may be ICT Support but I'm public facing enough that the general rule is "wear something that you feel is appropriate if you were to be called into a meeting with a customer at 2 minutes notice".
Each of us in the team interprets that differently, but that's fine by me.
Looking around it seems to be higher up the chain you go, the more formal you're attire becomes....so maybe I'm just casting the right vibes to be noticed by the next level up!! ;-)
I linked to this guy in the Chinese thread too, but this is relevant since he has strong opinions about work clothing. And he echoes many here in saying that people take you more seriously when you have a suit. And he was an IT guy. So Morty here might be on to something.

Yeah, it's all about how much importance you give to a situation, and that the people realize.
e.g. you often come a lot better dressed to your job interview than you'll ever show up in your job. Because you want to show that you'll consider this situation to be important. Not because you'll show up every day like this.
In the same way bankers and doctors need to be well dressed. Their matters are of high importance for the people they communicate with. Scientist and engineers on the other hand would not dress up, because they mostly communicate with people for whom the subject matter is just daily life.
If you then intentionally overdress, like the guy in the video, you'll radiate an aura of importance, giving the whole situation more worth.I guess I'd disagree with him that it's appropriate at most situations. While dealing iwth customers/clients yes, but if you're dealing with peers, you might come over as very pompous, IMHO.
