Attached Link: D-Form Plug-in

you can't apply a morph for a figure to a clothing item, morphs only work on the specific mesh they were created from. If the clothing doesnt come with a morph to fit than you will have to make one yourself. there are a couple of programs that can convert clothing for morphs but none of those will work as smoothly as using magnets to adjust the clothing, so I recommend learning to use the D-Form Plugin, and create your own morphs in the clothing to match the figure.
