Bathing suit malfunction?

I live at the beach so the other week I was in the water with my brother and some of his friends, just swimming in the ocean. I was wearing a bikini that was a little bit too big for me. So all of a sudden a huge wave comes, and I flip underwater a couple of times and when I come up I'm in more shallow water. I stand up, and I'm coughing and trying to get all the seawater out of my mouth when I hear my brother yelling at me to get down in the water. I'm like, What?!. So he runs over to me, and when he gets close enough, he grabs me by the shoulders and pushes me down in the water. Then he says, Your bathing suit bottom's gone! I look down and sure enough, I have on no bottom. My brother has to run the 5 minutes down to our house to get me a towel while I just sat in the water half naked. It was so embarrassing. Anyone else?
