Totally embarrassing moment

I am so mortified that this happened. I was doing some burpees at my Crossfit box and my (super oversized) t shirt must have caught a breeze from a fan and flipped up. Anyone near me would have seen my naked back and my bra strap. I can only hope that they didn't see me from the side. No one said anything, but there is no way that no one saw anything. Note to self - wear shirts that fit.

Anyone else have any stories like this? Am I alone?
