A female friend of mine at my first job loved to tell me about when she went water-skiing on holiday. She fell off the skis but did the beginner thing of forgetting to let go of the drag bar. She lost her bikini top completely - and had to walk topless back to the holiday apartment.
Sadly no photos exist!
