Me too, in Borneo. And again in Vietnam. Although on the same beach a group of Swedish girls took their tops off, so the attention was quickly diverted!

Regarding “know the local standards of dress”, I can tell you from personal experience that this tip is super important! I was in Tunisia about 5 years ago and was walking from my resort to the beach in a bikini and a somewhat see-thru cover-up. The looks I was getting was as if I had three heads. It was really uncomfortable and embarrassing.
