I wear the same shorts and shirt home that I wore riding in. I drape all my clothes over my bike to help to dry them/keep them from stinking too much. I'm lucky in this respect that I have a dedicated place to store my bike inside away from everyone else in the office. I always wash them when I get home. Putting on dirty clothes after you get out of the shower is not my bag. Of course I don't sweat a whole lot even in the summer.
