I went topless in Saint Lucia until there was a sudden rain squall and I had to run into the little beachside restaurant. There to my dismay I met a group of people I knew well, and I was topless. It was,,well,,,awkward.
Oh, dear.
After about 2 days, I went topless. I think we were the only Americans in our hotel and I felt overdressed after 2 days. But I was careful with the sunscreen :-)
