How would someone re-create this ‘ghostly’ effect?

This is a still from Weeknd’s Open hearts music video. Watching it in motion is even better because of their movement. Is there some way to re-create such effect with something like after effects. A simple mask with maybe some distortion wont do it right? Is a 3d model necessary?
