I don't think it's been suggested or meant by the maison, but I think this 5-piece ring set by Maison Martin Margiela would be good worn as a stack on one finger, and it need not be the bad one.
It is meant to be worn on all five digits like a knuckle ring for thugs.
Somehow this reminds me of geeky puzzles we had when we were kids: a kit of bent nails in the shape of triangles and circles etc etc that you had to configure in a certain way … I really cannot remember. The shapes I think come like paperclips linked to each other and the aim is to untangle them from each other … Oh I give up! Can you recall?
Whatever it is, seeing the rings like this, I am tempted to attach a chain at both ends and wear this as a bracelet.
