Most of time in past coaches wear what they wore to school that day. Which is why you saw khakis etc 
Now days with the free gear most get when ordering things they buy logo sweats and tops which is perfectly fine

No one makes the money college coaches do and on top for that most of the college coaches don’t pay for those suits lol 

NBA the richest highest most focal tv driven league in world wears pullovers and sweats with logos usually 

Times have changed 
And tbh it’s prolly for the better 
Much as high school coaches deal with daily
With parents admin etc
Last thing they need to deal with is worrying about what they wear 
When they are trying to win and work for nothing
