Here's my issue...

I was running along the road today and wondered why all of the people in their cars were staring at me. I realized as I walked up to a glass gym door at the end of my run that "my headlights were on." It was hot outside, so it's not the temperature. I'm thinking maybe it was the bouncing up and down from the running, but I have no idea how to fix it! I'm already wearing a sports bra, so I would think that would cover up the problem. Anyone have any ideas?
