I like Steph's body shape. Her slender look is great for a younger character. Or for wearing clothes. Steph looks great in clothes that make Vicky look fat. ;-)

I don't find Steph's breasts saggy, but if you make them too large, you notice a certain lack of smoothness. I suspect she doesn't have as many vertices in her chest as Vic.

As for her hands and feet...there's a free morph that makes them smaller.
