We've all been to Breakwater Beach, Hurricane Harbor or some water park and had this happen. We go down a slide and lose some clothing along the way. If you're lucky, it's a quick fix and nobody notices. The difference between us and Katy Perry is that we don't have paparazzi around us 24/7. Katy was spending an afternoon at a California water park when her bikini slipped down after riding a slide. This wasn't a partial reveal, we're talking full moon here.
