There's a pair currently working my town. I see them everywhere on their bikes. They wear helmets and I've never seen them on the sidewalk. I've never seen them wearing anything other than a white shirt and black pants, either. I don't think it's scandalous to wear just the shirt.

I did see one of them with a flat recently, walking his bike, and I would have offered to help them out, but I didn't really have time to talk.
