With such big hoops, comes a special wearing style. Will 6-inchers always rest on the shoulders, giving this "forward" look?

From my experience wearing them, I can tell that, unless you have a very long neck or you are tall enough (I guess if you are more than 1,8 metres tall they would hang a little bit when you stand up, but that's just a guess ), they will always rest on the shoulders. I agree that 90% of the time they will give that forward look you have said, the reason being their size. They can cover most of the face even if you don't interact with them.

The exceptions where they wouldn't give that look could be when you look up with them, when the hoops twist in the earlobes or some selfies postures
