"I had to learn in a regulation woollen Jantzen cozzy, which had so much drag it would have slowed people down, but I don't know whose regs it was or for what.

It certainly wasn't hard to get out of. Full of water, gravity could handle that, before I reached the changing room if I wasn't careful."

I've heard that in Rio they refer to the local bikinis-of-choice as "dental floss" - perhaps partly solving the drag problem..?
