In my last 2 "careers", I had graduated to ATGATT as far as riding gear went.
When I was GM at a Honda dealer, I had a company demo, but I still rode in a few days a month. I had a pretty big office, with a closet, my own bathroom, even, so I had a whole closet full of business suits etc. My admin asst always greeted me with "Good morning, Mr Power-Ranger"; my 'stich reminded her of the TV show, I guess.
anyway....
If you have to wear business attire, or look professional on the job, it ought to be pretty standard to have a stash of work clothing at your office or workspace, and a place to change. Dealing with helmet hair a whole other issue, though.
