I forgot that the bikini is quite large. If you have photoshop, you could make a render with bikini and without. Put the pics on separate layers (with bikini on on top) and then erase out some of the bikini (ie. make it smaller or even tube top like) and the underdressed parts from the render in the layer below will be revealed showing the texture. Or you could just draw something that looks like a tube-top or wrapping. I don't think the thread will hurt the texture sales though. Naturally, I sure hope not. : )
