Was at the beach in sweden once, and, there was this one girl doing a photoshoot for somethingy near the water, and, her bathing suit was literally this. 2 pieces of fishing line, 3 pieces of tin foil. 2 covering her nipples, and one covering her rump and stuff. Also, It was a 1 piece, because the fishing line went from the tin foil nipple cover, to the tinfoil vag cover
