I normally shower every ~3 days (yes, I shower every day if needed) and I put on clean underwear after a shower.  
ETA: I don't live in a disgusting humid state. It's dry. When I lived in Virginia I showered much more frequently. Humidity makes you disgusting.

I live in California, very very low humidity so to the point I am shocked about how humid it is when I visit other states. And right now, the temps are generally in the 50's - 70's Fahrenheit. Showering daily is an option, not a requirement/necessity. Same goes with changing what you're wearing.

 I am not getting sweaty and walking around in damp clothes all day, so might wear the same thing for more than a day. 

It's not really a big deal, and because I realized sometimes I wear the same clothes a few times before washing them, I actually ASKED a coworker of mine once if I was smelly, and he told me "what? No. Why?"
