I ride my bicycle 7 miles every morning at 5:30 am (to beat the heat and traffic). With the heat wave here in the Northeast, it has been hot and humid even early in the morning. This morning I got home and took my nylon shirt off to cool off in the A/C. When I laid my shirt on the floor, I noticed something that made me chuckle...there was a perfect outline of my sports bra on my back that was not wet. I wonder if anyone driving past me noticed? lol
