We go to Firefly where my wife does the topless thing and I go nude. She's a Brit, and having spent all her previous holidays in Europe, when she moved here she didn't even own a bathing suit top. When wandering off the Firefly property she grabbed a tee shirt and I usually wrapped myself in a sarong. The exception was a snorkelling trip to the reef. She went topless and I grabbed a thong. No worries mon.
