Just in case it's not what you're doing...to conform clothing, load the human model first, then the clothing. With the clothing selected, click on "Figure" -> "Conform to" and select the human model from the drop down menu. The clothing should then move with the figure whatever you do. Some clothing items don't get along well with IK. Select each figure in turn, click "Figure" -> "Use Inverse Kinematics" and remove any ticks that are in there. If you still get bits of the model showing through the clothing, the solution is either to tweak the clothing manually - using the scaling dials and/or magnets (not easy when you're new to it, I know), or to fix it in postwork (clone or smudge tools in photoshop or some other graphics program). If none of that helps...how about posting a couple of screenshots of the problem, so we can see more clearly what you mean. There's bound to be someone here who can help!
