Right now I'm commuting 7km round trip to work on my bike everyday on my old beater bike without bike shorts. Once things in the new office get settled down, I had planned on riding my C'dale to work and doing a ride at lunch time. I'll probably just ride to and from work in street clothes with my riding shorts in my bag and then just changing into them at lunch and then back out after the ride.

I know it's generally not a good idea to stay in a pair of sweaty shorts after riding, but does anybody just wear their riding shorts underneath their work clothes all day?
