Palma de Mallorca the beaches are topless. As an American I had to really adjust to that. Young girls, super hot twenty year olds (my age at the time), to pregnant mothers, they were all there. Didn't really see any old or obese women because they tend to stay away from the sun and do not really care for the beach. At first, it was a wild culture shock for sure. But honestly after a couple of hours, it became simply normal. How many boobs can you look at before you are desensitized?
On the side: saw my first real live actual bullfight there. That was another shock. To cut the story short, it is very far from a 'fair fight'. The bull is weakened in various ways before it is released. And even if it wins, it loses. But that is a different thread.
