My main carrier is US, and I'll often fly in their F (or, "F"

) cabin wearing neat but athletic clothing, which I prefer due to the comfort. But I've never flown "real" F, especially long-haul as detailed above.
Would it be inappropriate to wear
gym/casual pants like these, running shoes, and a t-shirt in "real" F cabins (and F lounges)? If so, what's the minimum attire in "real" F?
I am in the camp of wear whatever you feel comfortable in. I usually fly in shorts and a polo.
I am shocked that no one has gotten on you for only spending $12.99 for a pair of pants!!! There have been countless threads like this that seem to have FT'ers walking down a runway as opposed to landing on one.
There was a certain shoe one that comes to mind!
