None for me, but I agree some people just can't do it. Persoanlly, being in Texas I like as little on as possible. If I was small chested, I would only wear those shelf bra tops.
I take off my shorts immediately (sometimes in the car after a ride
) and wash every time. Only one bladder infection in 4 years riding and I have had one every few years for the last 13 years. I think it was just time for one, not anything to do with my bike shorts.
If you are going to wear undies I would recommend finding some for working out. They generally do not have noticeable seems and are moisture wicking. My friend swears by them for running. She won't just wear running shorts with the little built in liners.
