The cost can be endless depending on the available funds you have and what you're wanting to create with her. Certainly, aside from the purchase price of the V3 model, you can pick up freebies...but then you run into a lot of freebies that will only work depending upon owning a previously purchased "clothing pack" that you'll need to purchase to make them work. (i.e. they're textures to the original piece of clothing..there's no geometry file included). It's a vicious cycle and I'm ashamed to admit how much I've spent on my "hobby". ;)
