Dynamic clothe can be used in VWD (either Poser dynamic clothes or Daz Dynamic clothes). When vendor talk about a figure it means that the dynamic clothe, before simulation, is "fitted" on a zero pose/zero shape character (V4 for example). You can use a dynamic clothe in VWD on whatever character you want (genesis,...). But if you want a dynamic simulation of a V4 tee-shirt on a mouse (for example :-)) you might make some adjustments (sometimes with a dynamic simulation as VWD explained in one video tutorial, can't remember the one). Remember VWD use exported object coming from Poser or Daz so you can simulate whatever you want, imagination is the limit!
