I live in Australia and I often go to the beach to sunbake nude of course there aren't any legal nude beaches near me but I still do it. If there are people around when I want to go for a swim I just wear a c string. Again it covers the right areas so as not to offend anyone.
I wear a long and brightly coloured string vest, Carribean style. Oversized, but very like a dress when stretched to my thighs. Skin is almost entirely exposed to the sun, while the bright green color distracts the eye. I have cycled wearing nothing but the vest and shoes, for 20 miles to the beach, nobody even noticed. Of course, on a saddle, it folds discreetly in and nothing to offend is actually visible, even to the odd passing police cars
