One of the pleasures on the trip to Sint Maarten/St. Martin was being able to doff my bikini top to sunbathe and not worry about "accidents." Back home, in order to get an even tan, I unhook the back strap but leave the neck tied. That way, should I forget, the swimsuit hangs loosely but a little modesty is preserved. I undid both but forgot I did more than once . . . .
At St. Martin's you can go all the way!
