Victoria 1 (Vickie 1) and Victoria 2 (Vickie 2) share the same geometry (object file) but Victoria 2 has many more morphs to play around with. You can regard Vickie 2 as an evolution of Vickie 1, basicly the same model, but more versatile. Supermodel Vickie is a stand alone figure by Jim Burton, created from Vickies mesh. There is also a Supermodel Morph Vickie, which is a set of morphs to make the regular Vickie look like Supermodel Vickie.
