Kumite it might also be becourse the clothing you think you downloaded isn't clothing but only MAT poses for existing clothes. That would explain why it's in the Pose folder. If this is the case, then what you've downloaded isn't the clothing iself but only textures for it. What items are we talking about? It's likely something that requires Vickies Clothing pak or the like.
