The clothing you are working with is conforming and you cannot transfer morphs from the prop mannequin to this type of clothing.  It is possible, but not at your skill level.  You are casually dismissing the fact that there are 2 very different types of clothing, type one that conforms to the figure and type two that needs a cloth simulation to fit the figure.  One process cannot be applied to the other easily.
