A model is just a clothes hanger with a pulse. Such creatures are always subordinate to the rags they're shilling, and perhaps the zombie bit is just the look de jour.

With attention spans approximating those of a fish, the likely client for "fashion" needs to be seduced to even bother to look by whatever visual trick can be invented. I predict that models will pose as crime scene victims at some point in the near future when common sense and minimal taste has been completely abandoned.
