Basically, you put all of your favorite rings together and wear them. It's not really an easy trend to follow because there has to be some sort of harmony between the jewelry, otherwise it would look awkward and unbalanced.
But when the look is achieved right it looks unbelievably stylish.
These two ladies got it right!
My best advise is combine the simple with the out there. Maybe two extravagant rocks and two simple bands, with a funky one in between. Don't be afraid to combine silver and gold, it gives it that little bit of extra daring edge.
I also really like the Pandora rings to do these crazy combinations.
