recommended clothing for compromise betwee office and and biking home on a race bike?
"The facilities for changing clothes aren't there"


Yes they are, it's called a bathroom or a toilet stall, you don't have to have a locker room to swap a pair of pants, just wear your lycra for your ride and pack your clothes in your bag. Then change in the bathroom when you get to work.

Other than that, I once had a suit that was made out of wool-lycra, they're a little more expensive, but the material was certainly stretchy.
