It depends on the season I guess.
When I'm going to be seen by people, usually it's something like a plain solid color shirt, polo or button up (rarely going beyond a couple stripes) and jeans or shorts in the warmer months
In the winter, I dress like a sitcom dad or Drake in the below GIF:

a larger, dressier sweater and jeans.
If I'm not just hanging around at home, I have more of a slob aesthetic: an old t-shirt, gym shorts or sweat pants.
