I've seen this sort of thing before, and I cannot recall what caused it. Someone else here should know.

However, knowing that hameleon makes clothing compatible with Poser 7 and you're using Poser Pro 2014, if you're rendering with gamma correction turned on, the first thing I'd check is the gamma settings on trans, bump, and displacement maps. Unlike the color maps, these should have the gamma set to 1. (If you have GC on for this render, you could just test it by turning it off and seeing if it helps.)

In his readme, hameleon also says you must turn off smoothing. He also insists on enabling displacement. Have you checked those settings?

I may be way off the mark, but those are the things I would try first, while waiting for someone more knowledgeable than I am to reply.
