I had this problem constantly, and it was a combination of both of the above factors. So go to the render/materials window and be sure you either "apply to entire figure" (a bad idea with vicky, because she uses 2 textures!) or select "nipples" from the list of materials and set the texture on the nipples, AND make sure they're the same color as the body skin (white is the best, but if you're looking to darken down a texture without redoing it you can use a light color in the flesh ranges under it-just be sure to match it exactly to the other body parts). This problem will also crop up with the eyebrows & lips and so on when you're using a face texture. And the toenails and fingernails. But none of these are obvious in quite that same special way...my first set of poser renders were quite hilarious due to this problem, since I tend to "dress" posette in textures instead of prop clothes!
