The fact that my bra was showing somewhat was completely due to practicality. I had arrived at the beach at 6:45am, wearing a white tank top underneath, to make my outfit less...revealing. But it was already too hot, and I had to make a dash to the ladies restroom to take it off. I ended up showing (not in this photo, thankfully) quite a lot of my very sheer bra no matter how I moved.
