Real-time skinning or..?

Hello y'all
I'm wondering how one would go about doing realtime skinning of armour on a body.
I'm developing a game that's diablo like and trying to minimize the art effort.
Say I want this result:


basically because this has a lot of different body types from what I can tell the armour gets skinned on the body. I can't know whether they actually do realtime skinning but that would make more sense in order to have a realistic timeline.

Maybe someone else has a better way?

 

If the body types aren't too different from each other maybe blendshapes could handle it? That's how i fit the same clothes on different people in my game but the body types don't vary that much.

 

Path of exile has pretty different body types. If it were similar body types then the same armour model would fit too.
Also blend shapes would work I guess to show the deformation of the animation but isn't that also too much work? In the example they have 7 different body types
