In terms of shoes, chunky running sneakers are casual but converse or classic sneakers are more formal. Chelsea boots are more formal still.
A collared shirt worn unbuttoned and untucked over a tshirt is considered more dressy than just a tshirt.
This is likely going to continue. flipflops/sandals/slides will become the default shoe with any sort of actual closed shoe being considered formal.
Pyjamas have begun to appear in supermarkets, where people simply slide out of bed, get in their car, drive to the shop, buy what they need, then get back in bed, they see no reason to actually get dressed for something so socially unimportant. In fact it has almost become a deliberate fashion choice for some. They will probably start dressing like that for more things and it may become the norm.
I don't know what causes this as opposed to the opposite where fashion styles become more formal (ie, people didn't always wear 3 piece suits, they once wore simpler clothing but at some point the styles must have increased in formality). I suspect it has something todo with the level of seriousness in society, where life is dangerous and severe, it demands a serious approach to life, and with this comes more formal ways of dressing. The classic suit is a military uniform, the peak of severity.
Clothing began to casualise immediately after WW2 ended and we entered a time of unparalleled safety and relaxation
