If you have your clothing selected, and the figure you want to copy morphs from is wearing the clothing, you can go up to the top and select "Figure>Copy Morphs From" and then a drop down menu appears where you can select the figure you wish to copy the morphs from. Select that figure then you will have a window appear ( it may take a few moments) where you can select which morphs you want to appear. Select those morphs then hit OK and give it some time and the morphs will be included in the clothing. I hope this helps!
