Daring thin tights on a late night gym visit

I wore these for a run and workout at the gym the other night. There was only one person there and he only saw me from a distance. But the closed circuit cameras? I remember wearing this outfit a year ago an dthere was a young couple who walked in and worked out alongside me. I lost one of my earbuds and they helped me look for it. I remember having my ass thurts in the air in front of them as I looked under the treadmill. They didn't say anything, even though they got to see every bit of me through this very thin lycra/nylon outfit.
