While this is sort of confusing, I think the best whay to think of Stephanie is Vickie usings some of Mike's mesh (and there is no trace of Mike left, honest, it is more like Mike's UV mapping). And she has a set of morphs to change her into another character, Stephanie. It should be noted that DAZ's statements about her fitting Vickie's clothing is with the Stephanie morphs off, or else a rather loose fit. I think she has a much better shape than stock Vickie with the Stephanie morphs turned on (same shape with 'em off). Her joints don't work any better (or worse!), as she has all of Vickie's joint parameters. DAZ has gotten a little more real too, of her 4 breast size morphs only one makes them bigger! But I wouldn't say she can't be improved upon...
