In reply to Hidden:
I think the best way is a padded pouch with its own "belt," like a chalk bag. (I don't use a belt but rather a piece of cord I can tie, as I don't want a fastex buckle to be the only thing between my camera and oblivion.)
The advantage is that this allows you to spin the camera around behind you, to one side or the other, or to the front when you want to take pictures.
It is a good idea to tie stopper knots near the ends of your cord so that, if you untie and then accidentally drop one end, which is pretty easy to do, the camera doesn't slide off into the void (or onto a hard bathroom floor).
