#nojeans makes life more interesting, you've got to explore more options instead of the bland lazy one
Here are some options in order of formality –
Thai fisherman pants
Show
Workman's trousers like Snickers and stuff
Show
Heavy woollen trousers (as opposed to woollen slacks, which are suit-level formal)
Show
Linen trousers
Show
Slacks
Show
I find myself into these most days, does that make me Level 1.5 or 2.5?
(Otherwise I'll wear the normal pants version from the same brand. Comfy, practical, and jeans are boring, not that practical. Sometimes not even comfy.)
