you will probably need a converter as well, because Morphing Clothes only injects the morphs from a figure.
the three apps i know of are:-
Wardrobe Wizard by Philc ( built into the new P8 ) but can still buy standalone.
Clothes Converter
Crossdresser (available at EvilInnocence, need to buy 'convert to' licences for each figure. 'convert from' are free and come in 'support packs' the app itself is free.
i use Crossdresser with Morphing Clothes, but i believe the other two may give more control over the conversions.
