I believe I can say with reasonable confidence at this point that something is corrupt with the item file. Upon close inspection of the textured item in the pre-render document window, I see that while the texture is in fact applied, it looks very strange and distorted on the bikini top and bottom specifically. Funny thing is, it's only those two items that are affected. Others like the ankle boots, pants etc all work fine. Just the brown bikini top and bottom whose UV mapping must be screwed up. Unfortunately I don't quite know how to examine a "UV Map" file to get more specific information the problem.
