As TB says you might be able to adapt one of Master Box's 1/24th figures designed to go with autos.
I have seen this around though, one of the figures is sorta the same pose and dress:

If nothing else you can get Preiser's 32nd scale female nude set which includes a box of various parts that can be assembled as you please. You'd have to sculpt clothing of course:

(it might be cheaper to shop around, their price is insane, I paid about thirty-five for mine and thought it was too much)
