Which one is easier to render, you mean?

1.  Ginger.  There's so much more slutwear than farmgirl clothing out there.

2.  Jeannie.  Samantha has a quirkier face, Jeannie is more blandly pretty in a Poser sort of way.

3.  Tossup.  Darrin's face is quirkier, but he wears normal clothes.  It's not easy to find '60s military uniforms.

4.  Dick Sargent.  Dick York's eyes and chin would be harder to do in Poser, I suspect.

5.  Samantha.  It's still hard to get good curly hair in Poser.

6.  Tough one, but I say Jeannie.  Her sister had those tassly things on her headdress that add an extra level of difficulty.
